The amount of water for washing x cars is y = 12x, and 72 gallons would be needed to wash 6 cars.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
The standard form of a linear equation is given as:
y = mx + b
Where m is the rate of change and b is the y intercept (initial value of y)
Let y represent the amount of water Jaquan uses to wash x cars, Using the point (2, 24) and (5, 60):
y - 24 = [(60 - 24)/(5- 2)](x - 2)
y = 12x
For 6 cars:
y = 12(6) = 72
The amount of water for washing x cars is y = 12x, and 72 gallons would be needed to wash 6 cars.

Answer:
Sand: 21 parts.
Lime : 14 parts.
Cement: 7 parts.
Step-by-step explanation:
The number of parts is 3 + 2 + 1 = 6.
So for 42 parts we need:
Sand: 3/6 * 42 = 1/2 * 42 = 21.
Lime: 2/6 * 42 = 1/3 * 42 = 14,
Cement: 1/6 * 42 = 7.
