Answer:

A

Step-by-step explanation:

Given the 2 equations

3y = x - 1 → (1)

x - 2y = 2 → (2)

Rearrange (2) expressing x in terms of y by adding 2y to both sides

x = 2 + 2y → (3)

Substitute x = 2 + 2y into (1)

3y = 2 + 2y - 1 ( subtract 2y from both sides )

y = 2 - 1 = 1

Substitute y = 1 in (3) for corresponding value of x

x = 2 + (2 × 1) = 2 + 2 = 4

Solution is (4, 1)

joja [24]

Answer: 1.8125 gallons = 29 cups

Step-by-step explanation:

There are 16 cups in a gallon. Therefore, to convert gallons to cups we multiply the number of gallons by 16.

The number of gallons, in this case, is: 1.8125

So, we need to multiply 1.8125 by 16

1.8125 ⋅ 16 = 29

In the final analysis, 1.8125 gallons is equal to 29 cups.
