rasheed needs to save $231 to earn money he plans to wash cars and charge $12 per car write to estimates rasheed could use to determine how many cars he needs to wash

Answers

Answer 1

Answer:

Rasheed needs to wash 20 cars as washing 19 cars won't be $231.

What is an equation?

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, Rasheed needs to save $231 to earn money he plans to wash cars and charge $12 per car.

Assuming no. of cars he needs to wash is x.

∴ 12x = 231.

x = 231/12.

x = 19.25.

But he needs to wash 20 cars to meet his needs.

Well, we know the amount of cups of sugar it calls per 1/2 teaspoon, so all we need to do to find the amount of cups of sugar per teaspoon is multiply by 2, since 1/2 teaspoon * 2 = 1 teaspoon.

2/3 * 2 = 1 1/3

The unit rate is 1 1/3 cups per teaspoon
Hope that helped =)

per teaspoon means per 1 teaspoon
we know that the ratio is
2/3:1/2
we want to know
x:1
so
make them equal since they are in same ratio and fractionify
$( (2)/(3) )/( (1)/(2) )= (x)/(1)$
ok so easy peasy
(2/3)/(1/2)=x
2/3 times 2/1=x
4/3=x
4/3 cup

or you could recognize that 1/2 times 2=1 so therefor 2/3 times 2=x=

answer is 4/3 cup per teaspoon
