simplify the expression -6(3x-4)

Since the two horizontal lines are parallel, 4x+7=75

4x=68

x=17 or 17º

Answer:

x = 17

Step-by-step explanation:

(4x + 7) must equal 75

75 - 7

= 68

4x = 68

4x/4 = 68 /4

x = 68/4

x = 17

Step-by-step explanation:

y=8x

Answer:

y = -x + 9

Step-by-step explanation:

the equation of a line is given by y = mx + b where m Is the slope and b is the y intercept.

as shown in the graph, the y intercept is 9.

how to find the slope:

the slope is rise over run and as we can see that the points move down once and to the right once at every exact point. hence, the slope is -1.

the equation: y = -x +9

Step-by-step explanation:

Formula

The formula for perimeter is

P = 2L + 2w

Givens

Let the width = w

Length = 3w + 4

P = 80 cm

Solution

P = 2L + 2w

80 = 2(3w + 4) + 2w          Remove the brackets

80 = 6w + 8 + 2w              Combine

80 = 8w + 8                        Subtract 8 from both sides

80-8 = 8w + 8-8                 Combine

72 = 8w                               Divide both sides by 8

72/8 = 8w'8

9 = w

Answer

w = 9

L = 3*w + 4

L = 3*9 + 4

L = 31

Step-by-step explanation:

1. Calculate the 'Amount of sales tax':

Formula:

Amount of sales tax =

Sales tax rate × Price without sales tax

Calculation:

Amount of sales tax =

9.5% × 134 =

9.5/100 × 134 =

9.5 ÷ 100 × 134 =

0.095 × 134 =

12.73

2. Calculate the 'Price with sales tax':

Formula:

Price with sales tax =

Price without sales tax + Amount of sales tax

Calculation:

Price with sales tax =

134 + 12.73 =

146.73

Answer:

Amount of sales tax = $12.73 dollars;

Price with sales tax = $146.73 dollars;

Long division helps in breaking the division problem into a sequence of easier steps. Just like all division problems, a large number, which is the dividend, is divided by another number, which is called the divisor, to give a result called the quotient and sometimes a remainder.

The correct statement is A that is The average size of an eighth-grade class is smaller and varies less than that of a seventh-grade class.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations.

The mean of the seventh grade is given as 33.

The mean of the eighth grade is given as 30.

The correct statement is A because the mean absolute deviation of an eighth-grade class is less than that of a seventh-grade class.

Also, the class size is larger on average for seventh-grade classes (33 > 30).

The cost of each bag of onions that was purchased by Amira given the total amount spent and the cost of cookies is $6.46.

The first step is to determine the total cost of the 7 bags of onions.

Total cost of the 7 bags of onions = total amount spent - cost of cookies

$51.40 - $6.18 = $45.22

Now, divide the total cost of the 7 bags of onions by 7.

Cost of one bag of onion = 45.22 / 7 = $6.46

Answer:

The greater than or equal to sign is:

>= or ≥.

Now let's solve for this inequality.

-8x + 5 ≥ -3

First, we need to get rid of any constants.

Get rid of a constant by performing the inverse operation of it, we always apply this to both sides of an inequality.

The inverse operation of addition (since it is a positive 5) is subtractions.

So, we subtract 5 from both sides;

-5         -5

Now we have:

-8x ≥ -8

Now, all we need to do is isolate x from it's co-efficient, 8.

To do that, we also utilize the inverse operation.

The inverse operation of multiplication (since -8 is being multiplied by x) is division, we apply this to both sides of this inequality.

So, we divide by -8 from both sides;

÷ -8 ÷ -8

And we'll end up with:

x ≥ 1, therefore the solution to this inequality is 1.

Answer:

Radius = 2.8

Step-by-step explanation:

V = 1⁄3 πr² × h

50 = 1⁄3 πr² × 6

50 = 1⁄3 × 22⁄7 × r² × 6

50 = 22⁄21 × r² × 6

50 = 22⁄21 × 6 × r²

50 = 6.286 × r²

50 = 6.286r²

50/6.286 = 6.286r²/6.286

r² = 7.954

r = √7.954

r = 2.820

The student council sold long sleeve shirts for $12.50 and short sleeve shirts for $10.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the cost of long sleeve and y represent the cost of short sleeve, hence:

24x + 18y = 480     (1)

Also:

34x + 25y = 675    (2)

From both equations:

x = 12.5, y = 10

The cost of long sleeve shirts was $12.50 while short sleeve was $10 each.
