8 * 18 = 144
200 - 144 = 56
so $56 dollars would be left in your bank account
Fifth root of x is x^1/5 as an exponential expression. . This to the 7th power is
x ^(1/5 * 7) which is x^(7/5). Bringing this to the third power is x^ (21/5) which is your answer.
The second one is the best answer in my opinion i'm not sure.
False because, you DO add 4 to the sides but you would multiply the 8 because you to the opposite to cancel it out
Multiply by 0.4 on both sides to cancel the original 0.4 and change the 10
