Solve The Equation By Performing Two Operations On Both Sides. State The Operation In Order Of Use

Answers

Answer 1

Answer:

  C.  Multiply by 5, then subtract 7.

Step-by-step explanation:

You want to know the two steps required to solve this 2-step linear equation.

Solution

The variable x has 7 added to it, and the sum is divided by 5. To find the value of x, we must undo these operations in reverse order.

To undo division by 5, we must multiply by 5.

Then, to undo the addition of 7, we must subtract 7.

Here is the "work":

  [tex]\dfrac{x+7}{5}=10\qquad\text{given}\\\\x+7 = 50\qquad\text{multiply both sides by 5}\\\\x=43\qquad\text{subtract 7 from both sides}[/tex]

The operations in order of use are ...

  Multiply both sides by 5 first, then subtract 7 from both sides.

__

Additional comment

The properties of equality tell you that you must do the same operation to both sides of the equation.

Taylor and Alex are looking for a daycare for their child. They want to make sure the daycare is midway between their jobs. Taylor works at the Rogers Middle School located at (4, -5), and Alex works at St. Philip's located at (2, 5). Where should the daycare be located?

Answers

The location of the coordinate of the daycare is (3, -1.5)

Midpoint of coordinates

The formula for calculating the midpoint of coordinate is expressed as;

M(x, y) = {(x₁+x₂/2, y₁+y₂/2)}

Given the coordinate points (4, -5) and (2, 5), on substituting, we will have:

M(x, y) = {(4+2/2, -5+2/2)}

M(x, y) = (6/2, -3/2)

M(x, y) = (3, -1.5)

Hence the location of the coordinate of the daycare is (3, -1.5)

the total weight of henry peter and david is 123.peterr is 15 kg hevier than david. david is 3kg lighter than henry find henrys weight

Answers

The ages will be:

Henry's weight = 38kg

David =35kg

Peter = 50 kg

How to calculate the weight?

Let Henry's weight be represented by x

David is 3kg lighter. This will be x-3.

Peter is 15kg heavier. This will be:

= x-3 + 15 = x +12

This will be:

x + x-3 + x + 12 = 123

3x + 9 = 123

3x = 123 - 9

3x =114

Divide

x = 114/3 = 38

Therefore, Henry's weight = 38kg

David =x - 3 = 38 - 3 = 35kg

Peter =35 + 15 50 kg

The measure of one angle is four times the measure of its supplement. Find the measure of each angle.

Answers

The measure of the angle is 36° and its supplement is 144°.

The supplement of an angle is calculated by subtracting the value of the angle from 180°.

A linear pair of angles are supplement of one another.When two straight lines intersect at a point then any 2 adjacent angle of the four angles formed are supplementary angles. In a cyclic quadrilateral ( quadrilateral whose 4 sides touch the same circleat different points ) opposite angles are supplementary.

Given that the supplement of the angle is 4 times the angle.

Let us consider the value of the angle be x°.

Therefore the value of the supplement is 4x°

Now the sum of the two supplementary angles is 180°.

∴x° + 4x° = 180°

or, 5x° = 180 °

or, x° = 36°

Therefore the larger angle = 4x° = 4 × 36° = 144° .

Hence the angles are 36° and 144° .

A survey of 279 SPC students was taken at registration. Of those surveyed: 51 students had signed up for a Language Arts course 36 students had signed up for a Humanities course 18 students had signed up for both a Math and Language Arts course 8 students had signed up for both a Math and Humanities course 9 students had signed up for both a Language Arts and Humanities course 4 students had signed up for all three courses students did not sign up for any of these classes How many students signed up for only Math (of these three)?

Answers

Treating the amounts as Venn sets, we have that 161 students signed up for only Math, considering that 40 did not sign for any.

What are the Venn sets?

For this problem, we consider the following sets:

Set A: Students that have signed up for Arts.Set B: Students that have signed up for Humanities.Set C: Students that have signed up for Math.

4 students had signed up for all three courses students, hence:

(A ∩ B ∩ C) = 4.

8 students had signed up for both a Math and Humanities, hence:

(B ∩ C) + (A ∩ B ∩ C) = 8

(B ∩ C) = 8.

18 students had signed up for both a Math and Language Arts, hence:

(A ∩ C) + (A ∩ B ∩ C) = 18

(A ∩ C) = 14.

9 students had signed up for both a Language Arts and Humanities, hence:

(A ∩ B) + (A ∩ B ∩ C) = 9

(A ∩ B) = 5.

36 students had signed up for a Humanities course, hence:

B + (A ∩ B) + (B ∩ C) + (A ∩ B ∩ C) = 36

B + 5 + 8 + 4 = 36

B = 19.

51 students had signed up for a Language Arts course, hence:

A + (A ∩ B) + (A ∩ C) + (A ∩ B ∩ C) = 36

A + 5 + 14 + 4 = 51

A = 28.

Considering that there are 279 students, and supposing 40 did not sign for any course, we have that:

A + B + C + (A ∩ B) + (B ∩ C) + (A ∩ C) + (A ∩ B ∩ C) + 40 = 279.

28 + 19 + C + 5 + 8 + 14 + 4 + 40 = 279

118 + C = 279

C = 161

161 students signed up for only Math, considering that 40 did not sign for any.

Answers

A fraction is a way to describe a part of a whole. Beth will able to fill 5 complete bottles from a single batch of liquid cleaner.

What is a Fraction?

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

Given that the recipe makes ⅔ gallons. Also, Beth puts cleaner in ⅛ gallon bottles. Therefore, we can write,

Total batch size = ⅔ gallons

Size of a bottle = ⅛ gallon

Now, the number of bottles that Beth will be able to feel from a single batch of liquid cleaner is,

Number of bottles = Total batch size / Size of a bottle

                               = ⅔ gallons / ⅛ gallon

                               = (2×8) / (3×1)

                               = 16 / 3

                               = 5.3333 ≈ 5

np bisects MNQ, measurement MNQ, measurement MNP = (6X-12)° and measurement PNQ = (4x+8)°. find measurement MNQ​

Answers

The Required answer is ∠MNQ is (10x - 4)°

Two unique points on a line define the boundaries of a line segment. A line segment is sometimes referred to as a section of a line that links two places. The difference between a line and a line segment is that a line has no endpoints and can go on forever in either direction.

Given NP bisects MNQ as shown in the given figure

A line segment that bisects two lines divides them into two equal parts.

Given ∠MNP =( 6x - 12)°

Given ∠PNQ = (4x + 8)°

We have to determine ∠MNQ as

∠MNQ = ∠MNP  + ∠PNQ

           = 6x - 12 + 4x + 8

The number of sweaters that Jaylen will purchase, based on his marginal benefit, is 5 sweaters.

What is marginal utility?

Marginal utility or benefit is the added satisfaction that a consumer derives from the consumption of an additional unit of a product or service.

Using the concept of marginal utility, we can determine the number of units consumers will be willing to purchase.

The law of marginal utility states that a consumer will continue to purchase more of an item until their marginal benefit or utility is fewer than the cost of the item.

For instance, Jaylen will buy sweaters until his marginal benefit is lower than the price of a sweater ($10).

Jaylen is likely to buy 5 sweaters since his marginal benefit, though progressively reducing, still exceeds the price of the sweaters.

Data:

Price per sweater = $10

                     Marginal Benefits

1st sweater              50

2nd sweater           35

3rd sweater            30

4th sweater            23

5th sweater            12

C is the correct choice.

Step-by-step explanation:

Here are the rules for vertical stretches and reflection

Given a function f(x), a new function [tex]g(x)= a \cdot f(x),[/tex] where a is a constant, is a vertical stretch or vertical compression of the function f(x).

If a>1, then the graph will be stretched verticallyIf 0<a<1, then the graph will be compressed verticallyIf a<0, then there will be combination of a vertical stretch or compression with a vertical reflection around the x-axis

Since the question use a multiplicative of -3, and -3 < 0 we get the correct choice as C: The graph of g is the graph of f vertically stretched by a scale factor of 3 and reflected over the x-axis

Answer: The first step in determining the solution to the system of equations algebraically is [-4,-2].

Step-by-step explanation:

Determining the solution to the system of equations,

so, y=-x²-4x-3 and y= 2x+5, algebraically is to set the two equations are equal to:

-x²-4x-3 =2x+5

Then the solve in this equation

To put all terms into the lest side of the equation and group the terms:

solve it:   -x²-4x-3-2x-5=0

-x²+(-4x-2x)+(-3-5)=0

-x²-6x-8=0

now you can multiply this equation by -1

x²+6x+8=0

and solve it using Quadratic equation

x(1,2)=[-b±√[tex]b^{2}[/tex]-4ac]/2a

replace with a=1,b=6,c=8 values
