the expression is 27a^3 or (3a)^3
Use elimination
Multiply first equation by 4
12a - 8b = 56
12a + 9b = 39
Subtract both
-17b = 17
b = -1
Plug in -1 for b
3a - 2(-1) = 14
3a = 12, a = 4
Final answer: a = 4, b = -1
Answer: 9/12
Step-by-step explanation:
1. 1/4+2/8 (common denominators)
2/8+2/8=4/8 or 1/2
2. 1/2+3/12 (common denominators)
6/12+3/12= 9/12
Answer:
16%
Step-by-step explanation:
so you already know 35% like both and 17% like apples and 32% like neither
add those and get 84. we know that the percent is over 100 . So far you have 84% meaning there is only 16% left . Therefore 16% like bananas
