<span>Simplifying 24x + 2y = 48. Solving 24x + 2y = 48.
Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
24x + 2y + -2y = 48 + -2y.
Combine like terms: 2y + -2y = 0 24x + 0 = 48 + -2y 24x = 48 + -2y.
Divide each side by '24'.
x = 2 + -0.08333333333y Simplifying x = 2 + -0.08333333333y</span>

Isolate x.
24x = 48 - 2y

Divide by 24.
x = 2 - y/12

Josephine is on a cell phone plan where she pays $20 a month plus $.10 per text message she does not want to spend more than $40

puteri [66]

Answer:

She can send 200 messages....

Step-by-step explanation:

We have given:

Josephine is on a cell phone plan where she pays $20 a month plus $.10 per text message she does not want to spend more than $40 on her cell phone bill

The equation we get is:

20+0.10x<=40

Now solve the inequality:

20+0.10x<=40

Combine the like terms:

0.10x<= 40-20

0.10x <= 20

Divide both sides by 0.10

0.10x/0.10 <= 20/0.10

x <= 200

She can send 200 messages....

A new car is purchased for $50,000 and over time it’s value depreciates by one half every 5 years. What is the value of the car

Setler79 [48]

The value of the car after 5 years would be $23914.85

<u>Explanation:</u>

Given:

Worth of the new car = $50,000

Every 5 years the value depreciates by 1/2

i.e., every 5 years the value depreciates by 50%

So, we can say that every year the value depreciates by 10%

The worth of the car after 7 years would be

$W = C (1 - \frac{D}{100} )^t$

where,

W is the depreciated value

C is the current value

D is the depreciation rate

t is the time

Substituting the value in the equation we get:

$W = 50000( 1 - \frac{10}{100} )^7\\\\W = 50000 (\frac{9}{10} )^7\\\\W = 23914.85$

Therefore, the value of the car after 5 years would be $23914.85
