In the second to last part, there should have been a 4 added to the right side instead of subtracted, making it x=5 and not x=-3

You put it in a little weird in that part too, watch out for that next time. The 4 that should've been in the second to last part looked like it was being multiplied by the x in the last part

Answer:

x y

3 3

5 7

1/2 -2

-1 -5

Step-by-step explanation:

You have to plug the numbers in to find out the chart

2(3)-3=y

6-3=y

3=y

2x-3=(7)

add the 3 on both sides to make the x by its self

2x=10

divide both sides by 2

x=5

2(1/2)-3=y

1-3=y

y=-2

2x-3=(-5)

add the 3 to both sides

2x=-2

divide the 2 on both sides

x=-1

Substitute x=3 in the given equation
We get 2(3)-3=y
6-3=y
So, y=3
next, substitute y=7 in the equation
We get 2x-3=7
2x=7+3
2x= 10
X= 5
Keep substituting the values..
When x= 1/2, Y = -2
When y= -5, x= -1

3c + 1 = 10 Need help with this I have so many assignments to do Help me Please and Thank you!

Answers

Answer:

c = 3

Step-by-step explanation:

You are solving for the variable, c. Isolate the variable c. Note the equal sign, what you do to one side, you do to the other.

Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, subtract 1 from both sides of the equation:

3c + 1 = 10

3c + 1 (-1) = 10 (-1)

3c = 10 - 1

3c = 9

Next, divide 3 from both sides of the equation:

(3c)/3 = (9)/3

c = 9/3

c = 3

c = 3 is your answer.

~

c = 3 because 3 x 3 is 9 + 1 is 10

Is the equation just solve for x

Answer:

Tammy home is 21 miles away from the airport.

Step-by-step explanation:

I tried out different numbers and either had to go up or go down. You'll have to make sure the decimal ends with .10 because she tipped the driver $5 and no change. 2.10 x 21 = 44.1 plus the $5 tip it would be $49.10

If ABC is a right triangle, and m∠A=40º, what are possible measures for B and C? (I forgot the screenshot so sowy ;w;*

Answers

There is many answers to this question but angle B and C have to add up to 140 so angle B and C could both be 70 that should work

Answer:

The other possible angles would be 90º (Right tringles always have a 90º angle) and 50º

Step-by-step explanation:

To find the 3rd angle (the 50º one) all tringles angles add up to 180º. Since you already have 40º and 90º

you would subtract those from 180.

180º - 40º - 90º = 50º

At a grocery store, you can buy a 20-ounce of peanuts for $3.59, or you can buy a one-pound (16 ounces) package for $2.59. Why is the one-pound package the better deal? Explain your answer by talking about unit rates.

Answers

Answer- The one pound package is a better deal because it costs 32 cents per ounce rather than the 20 oz, which charged 45 cents per oz.

Explanation- let’s convert all units to ONE OUNCE. 3.59/20(oz)= 0.45, do 45 cents per ounce for the first. For the second, we know that one pound is 8 oz so divide 2.59 by 8 and you get 32 cents per oz. We know that if we are getting 8 oz for 32 cents per ounce, it is the better deal rather than 45 cents per oz.

Starting at 1:00 p.m., the temperature changes -4 degrees Fahrenheit per hour. Write an equation to find how many hours it will take to reach -1 *F.

Answers

Answer:

35 x (-4x) = -1           (9 hours)

Step-by-step explanation:

If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.

35 x (-4x) = -1

-4x = -36

x =  9

35 x (-4x) = -1  (9 hours)

Step-by-step explanation:

If your original temperature is 35, you can place that as your first term. Knowing that the temperature changes by -4 degrees per hour, we can make "x" = the number of hours until we get to -1° F.

35 x (-4x) = -1

-4x = -36

x =  9

Step 2: 2×3/3×4

Step 3: 2×3=6

Step 4: 3×4=12

Step 5: 6/12

Step 6: Simplify 6/12 = 3/6 = 1/2

You drink half of the water in the bottle is 2/3 full.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given the following data;

A bottle of water is 2/3 full. You drink 3/4 of the water.

To determine the portion of the bottle of water that you drink.

To do this we would multiply 2/3 of a bottle of water by 3/4.

⇒ 2/3 × 3/4

⇒ 6/12

⇒ 1/2

Thus, you drink half of the water in the bottle is 2/3 full.

Answers

step 1

find the coordinates of the factory

the factory is 104 miles due north of the warehouse

the coordinates of the warehouse are (39,-52)

coordinates of the factory------> (39,-52+104)------> (39,52)

step 2

find the distance warehouse to airport

let

A coordinates of warehouse-------> A( 39,-52)

B coordinates of airport---------> B(-39,52)

C coordinates of factory-------> C(39,52)

distance AB=√[(52+52)²+(-39-39)²]------> distance AB=130 miles

step 3

find the distance airport to factory

B(-39,52)

C(39,52)

distance BC=√[(52-52)²+(39+39)²]-----> distance BC=39 miles

the total number of miles=distance AB+distance BC---> 130+39

the total number of miles=169 miles

Thus the answer is 169

Two lines have the same non-zero y-intercept. The first line has a slope of 10 and an x-intercept of (s, 0). The second line has a slope of 6 and an x-intercept of (t, 0). What is the ratio of s to t? Express your answer as a common fraction.

Answers

Answer:

         

Step-by-step explanation:

A line is a one-dimensional shape that is straight. The ratio of s to t is 3/5.

What is the equation of a line?

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

Given the first line has a slope of 10 and an x-intercept of (s, 0). Therefore, if the coordinate of the x-intercept and slope is substituted in the equation of line. Then, the equation can be written as,

y = mx + c

0 = 10s + c

c = -10s

Also, given the second line has a slope of 6 and an x-intercept of (t, 0). Therefore, if the coordinate of the x-intercept and slope is substituted in the equation of line. Then, the equation can be written as,

y = mx + c

0 = 6t + c

c = -6t

Further, since the y-intercept of the line is equal for both the line, therefore, we can write,

c = c

-10s = -6t

s/t = -6/-10

s/t = 3/5

Hence, the ratio of s to t is 3/5.
