The Green family is a family of six people. They have used 4,885.78 gallons of water so far this month. They cannot exceed 9,750
prohojiy [21]

Answer:

The inequality is  6x+4,885.78\leq 9,750.05

x\leq 810.71\ gal

Step-by-step explanation:

Let

x -----> amount of water that can be used by only one family member for the rest of the month

we know that

6x+4,885.78\leq 9,750.05

Solve for x

Subtract 4,885.78 both sides

6x\leq 9,750.05-4,885.78

6x\leq 4,864.27

Divide by 6 both sides

x\leq 4,864.27/6

x\leq 810.71\ gal

Knowing this, you can conclude that your answer would be choice B.)3

Today, Reza ate 20 grapes, which was 400% as many grapes as he ate yesterday. Explain how to use equivalent ratios to find the n
Yanka [14]
What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.
 To do it, let:
 x: number of grapes that Reza ate yesterday
 (x / 20) = (100/400).
 Clearing x we have:
 x = (100/400) * (20) = 5
 answer
 the number of grapes Reza ate yesterday was 5
