Two numbers that are each 2 units from -7 are -5 -9
5 quarts = ?
⇒ 1 cup = 0.25 quarts
⇒ 0.25 ÷ 5 = 20 cups
⇒ 5 quarts = 20 cups
The answer is 26.
This is because, since y is equal to 8, you would put 8 in replacement of y, which is called substituting. It would look something like this.
2 + 3y
2+ 3(8)
2+ 24
26
Add 29 and 18 first to get to get 47 then add 47 and 21 to get your final answer that is 68
