290-180=110

110/22=5

Answer 2

Answer: 5

Explanation:

If Cather added the ages of a crowd of both 18-year-olds and 22-year-olds and got 290, we can write that as 18x+22y=290. Knowing that there were 10 18-year-olds, we can plug 10 in for x.

18 times 10 + 22y = 290

So, first, we should multiply.

18 times 10 is 180, leaving us with 180+22y=290

Next, we should subtract both sides by 180.

So, 22y=110

Finally, we need to divide both sides by 22.

Leaving us with the answer of 5.
