Please be more clear on what you want us to do
She used 200 pounds of cheese and 20pounds of lettuce. So 220 pounds together
Option B is your answer.
3/5x - 5 + 5/5x - 4 = - 1
8/5x - 9 = - 1
8/5x = - 1+ 9
8/5x = 8
Multiply both sides by 5/8 (the reciprocal of the coefficient) to isolate variable X.
(5/8)(8/5x) = 8(5/8)
x = 40/8
x = 5
1+3=4
A counterexample is an a example that proves the statement false.
1+3 are not even numbers but they equal an even one, so it just proved the statement wrong.
