Answer:
ok i already did ur paragraph is that it
Answer:
-1/8 :)
its like saying -2 to the power of 1/3, it gets you -1/8
Cross multiply
10/a = 15/30
10/a(a)(30) = 15/30(30)(a)
Simplify
1/a(a) = 1
15/30(30) = 15
10(30) = 15(a)
Simplify. Combine terms
300 = 15a
Isolate the a. Divide 15 from both sides
300/15 = 15a/15
a = 300/15
a = 20
A) a = 20 is your answer
hope this helps
