4 because if you divide 120/30 you get 4
B i think the answer is for #5
Hello!
You can only add variables with the same base and exponent
8u^3 + 4u^3 = 12u^3
8u^2 + 0 = 8u^2
0 + -6u = -6u
6 + 3 = 9
Put the sums together
12u^3 + 8u^2 - 6u + 9
The answer is
Hope this helps!
= .91(.85)(.82) = .63427
<span>or 63.427% of the original price
so your answer is B</span>
Let n represent the number.
1/3n = n - 12
