There are 2820 cars in Farmington. The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size ca
oee [108]

Answer:

Number of full size cars = 900

Step-by-step explanation:

The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size cars is 8 to 9. Since compact cars are  there in both ratios , we need to  make the number in the ratio for compact cars to be the same.

\frac{medium}{compact} = \frac{7}{5}

Multiply by 8 on numerator and denominator

\frac{medium}{compact} = \frac{56}{40}

\frac{compact}{full size} = \frac{8}{9}

Multiply numerator and denominator by 5.

\frac{compact}{full size} = \frac{40}{45}

Ratio of medium, compact and full size are in ratio 56,40,45.

Total number of cars =2820.

(56 + 40 + 45)x = 2820

x = \frac{2820}{141}

x = 20

Number of full size cars = 20\times 45 =900

I'm thinking of a number. If you multiply it by 5 and then subtract 24, you will get -44. What is my number?
Allushta [10]

Answer:

4

Step-by-step explanation:

let y = the number

y x 5 - 24 = -44

y x 5 = -44 + 24

y x 5 = 20

y = 20/5

y = 4

In six years, clem kadiddlehopper will be five time as old he was 26 years ago. how old is he now?
levacccp [35]

Answer:

he is currently 34

Step-by-step explanation:

x + 6 = 5(x-26)

x + 6 = 5x - 130

 +130        +130

x + 136 = 5x

-x             -x

136 = 4x

/4       /4

x = 34

You can check your work as well:

34 + 6 = 40

34 - 26 = 8

8 x 5 = 40
