Yes they are equivalent. This is because if you simplify each fraction : 288/12 and 240/10 they both equal 24.

8x - 19 = 36
8x = 55
x = 55/8 = 6 7/8
-2x + 19 = -66
-2x = -85
2x = 85
x = 42 1/2
1.75
4 x 1.75 = 7 so that is the answer
Answer:
765
Step-by-step explanation:
4500x8,5= 38250/100=382,5 x2= 765
-7 - 12 = -1(7 + 12) = -1(19) = -19
Your answer is A.
