Find the unit rate. Unit rate from chart

Answers

Answer:

I don't see a chart

Answer:

The unit rate is 15.

Explanation:

Time (hours)

6: $90 90/6 = 15

12: $180 180/12 = 15

18: $270 270/18 = 15

24: $ 360 360/24 = 15

You should find the unit rate by dividing y by x. I divided all of the y's by the x's and I got 15 for all of them, which means that the unit rate is 15.

Answer:

x = 7/3

Step-by-step explanation:

3x - 2 =5

Add 2 to each side

3x-2+2 = 5+2

3x = 7

Divide by 3

3x/3 = 7/3

x = 7/3

Answer:

x = 7/3

Step-by-step explanation:

So there's 3 x's, two -1s and 5 +1s.

3x + (2 * -1) = (5 * 1)

Multiply 2 times -1 and 5 times 1.

3x - 2 = 5

Add 2 to both sides (to cancel out the minus 2.)

3x - 2 + 2 = 5 + 2

3x - 0 = 7

3x = 7

Now, divide both sides by 3 to get the x by itself (so you end up with x = something).

(3x)/3 = 7/3

3/3 simplifies to 1 so you end up with:

x = 7/3

Step 2:

124° = x Add

Answer:

x = 124°

Hope This Helps :)

Answer:

D) 124°

Step-by-step explanation:

Use the "Exterior Angle Theorem". The Exterior Angle Theorem states that the exterior angle's measurement is the sum of the two opposite interior angle's measurements.

In this case, it is given to you that the opposite angle's measurements are 72 and 52 degrees respectively. To solve, combine the two angles:

m∠x = 72 + 52

m∠x = 124°

m∠x = 124°, or D) 124° is your answer.

A community center charges x dollars for a summer activity if individuals are signed up before the day of the activity. Individuals who sign up the day of the activity are charged a fee of x plus 0.20 x dollars. Which expression also represents the fee for signing up the day of the activity, and what does it mean about the fee?

1.2 x; individuals signing up the day of the activity get charged 20% more

0.8 x; individuals signing up the day of the activity get charged 20% more

1.2 x; individuals signing up the day of the activity get charged 20% less

0.8 x; individuals signing up the day of the activity get charged 20% less

Answers

A is the answer to the question

The correct option will be "Option A."

It is given that a community center charges x dollars for a summer activity before the day of activity and on the day of activity they charge x plus 0.20x dollars.

We have to find the expression on day of activity and what is correct statement about the fee.

What will be the value if we add x with 2x ?

The value will be 3x.

Let's translate the problem to an equation we can work with:-

Before the day of activity, fee = x

On the day of activity fee will be ,

x + 0.2x

Because x and 0.2x are both in terms of the same variable x, we can add them together:

1.2x = fee on the day-of-activity

So, individuals signing up the day-of the activity are charged 1.2x and because 20% of 1 is 0.2, individuals are charged 20% more on the day-of-activity.

Thus , the correct option is "option A".

What is estimation?

Estimating in maths is a way of approximately calculating an answer or to check its accuracy.

Given that, Julie figures that she will need at least 540 Marks (German money) to get the items she wants when visiting Germany.

To find how much currency she should carry, we will convert the US currency into German currency

$1.06 = €1

Therefore, €540 = 1.06x540 = $572.64

Hence, The estimated money Julie should carry with herself is $572.64
