if car is worth $40,000 and then ten years later it is worth $24,000 express the cars value in dollars as a function of time

Answer:If Mary spent half of her allowance the equation will begin with 1/2x or 0.5x where x is her allowance and 0.5 is half of her allowance spent. Mary also earned 7 dollars by washing the car so this will be added to her allowance spent.

The problem says that after Mary has spent half of her allowance at the movies she was left with 18 dollars so that means that the equation must be equal to 18.

The equation you want to set up is

0.5x+7=18

Where, 18-7=11

0.5x=11

11/.5 = x

x = $22

Thus, Mary has a weekly allowance of 22 dollars.

What is 2.125 as a fraction?

Nuetrik [128]

2.125 = 17/8 = 21/8 as a fraction

Step by Step Solution

To convert the decimal 2.125 to a fraction follow these steps:

Step 1: Write down the number as a fraction of one:

2.125 = 2.125/1

Step 2: Multiply both top and bottom by 10 for every number after the decimal point:

As we have 3 numbers after the decimal point, we multiply both numerator and denominator by 1000. So,

2.125/1 = (2.125 x 1000)/(1 x 1000) = 2125/1000.

Step 3: Simplify (or reduce) the above fraction by dividing both numerator and denominator by the GCD (Greatest Common Divisor) between them. In this case, GCD(2125,1000) = 125. So,

(2125÷125)/(1000÷125) = 17/8 when reduced to the simplest form.

As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 2125/1000 is also equal to 2 1/8 when expressed as a mixed number.
