Serhud [2]

Answer:

24 cars

Step-by-step explanation:

Given

$Red:Blue = 3:2$

$Cars = 40$

Required

Determine the number of red cars

Number of red cars is calculated using:

$Red\ Cars = \frac{Red\ Ratio}{Total\ Ratio} * Cars$

$Red\ Cars = \frac{3}{3 + 2} * 40$

$Red\ Cars = \frac{3}{5} * 40$

$Red\ Cars = \frac{3 * 40}{5}$

$Red\ Cars = \frac{120}{5}$

$Red\ Cars = 24$

Evaluate 3x+4(y+3) when x is 5 less than the quotient of y and 3, and y=18.

romanna [79]

It is given that x is 5 less than the quotient of y and 3.

And given value of y is 18 .

So quotient of y and 3 is

$\frac{18}{3} = 6$

And 5 less than 6 =1

So we have y=18 and x=1

Given expression is

$3x+4(y+3)$

At x=1 and y=18, we will get

$3(1)+4(18+3) =3 + 4(21)$

$= 3+84=87$
