Answer:
Step-by-step explanation: make sure that a+b=180
for you'll get the answer
Answer:
63
Step-by-step explanation:
so y/3 - 9 = 12, add 9 on both sides and you get y/3 = 21. Then you multiply both sides by 3, y/3 * 3, the 3's cancel out, 21 * 3 = 63. You get y = 63
So basically just do + 9 on both sides then *3 on both sides (do it step by step)
Answer:
B x^9 ∛ y
Step-by-step explanation:
(x^27 y) ^ (1/3)
x^27^(1/3) y^(1/3)
We can distribute the exponent a^b ^c = a^(b*c)
x^(27*1/3) y^(1/3)
x^9 y^(1/3)
29.87 should be it hopefully
