Answer:
the answer is 5
Step-by-step explanation:
2x/5 - 9 = -7
2x/5 = -7 + 9
2x/5 = 2
2x = 2 * 5
2x = 10
x = 10/2
x = 5
Write a literal equation for a.
18/a=7
Multiply both sides by a
18=7a
Then divide both sides by 7
18/7=a
Final answer: B
(8, 11) is the correct solution. x = 8, y = 11
Plug it in:
11-8=3
That's correct.
It would be 12 because you have to solve for the percent
19 because 1 ten = 10 ones and 9 one plus 10 ones equals 19 altogether
