Mathematics

Answer:

Step-by-step explanation:

Let x represent the number of cars that Jamie washes.

Let y represent the number of pies that Stella makes.

The amount of money needed by Jamie and Stella to sign up for the trip is $600 each

Jamie earns $25 for each car washed. This means that if he washes x cars, he would earn 25×x =$25x

Stella earns $15 for each pie made.

This means that if she makes y pies, she would earn 15×y =$15y

Part 1) The inequality is

25x greater than or equal to 600

Part 2)The inequality is

15y greater than or equal to 600

Part 3) Stella only has enough supplies to make 40 pies. Total amount made from 40 pies would be 40×15 = 600

Jamie's earnings is

25x greater than or equal to 600

Stella's earnings is

15y lesser than or equal to 600

Part 4) Maximum amount of money that Stella can earn is 15×40 = $600

Therefore, Stella can afford to sign up for the trip.

A bus traveled on a level road for 4 hours at an average speed of 20 miles per hour faster than it traveled on a winding road. T
Kruka [31]

To solve this problem, we must recall that the formula for velocity assuming linear motion:

v = d / t

Where,

v = velocity

d = distance

t = time

 

For condition 1: bus travelling on a level road

v1 = d1 / t1

<span>(v2 + 20) = (449 – d2) / 4                        --->1</span>

 

For condition 2: bus travelling on a winding road

v2 = d2 / t2

<span>v2 = d2 / 5                                            --->2</span>

 

Combining equations 1 and 2:

(d2 / 5) + 20 = (449 – d2) / 4

0.8 d2 + 80 = 449 – d2

1.8 d2 = 369

d2 = 205 miles

 

Using equation 2, find for v2:

v2 = 205 / 5

v2 = 41 mph

 

Since v1 = v2 + 20

v1 = 41 + 20

v1 = 61 mph

 

Therefore <span>the average speed on the level road is 61 mph.</span>

Can you help me explain
stepladder [879]

Answer:

x = 10

Step-by-step explanation:

We need to isolate X.

3x - 7 = x + 13

subtract 13

3x - 7 - 13 = x

combine like terms

3x - 20 = x

subtract 3x

- 20 = x - 3x

Combine like terms

- 20 = - 2x

Divide by -2

10 = x
