Let's call the original amount of money x.
We know that she has 2/5 of the original amount left, and that this is equal to $15.
Therefore, 2/5(x) = 15, and x = $37.50.
Answer:
49
Step-by-step explanation:
7^x
If x=2
7^2
49
Square Area ( A square has all equal sides) = L x W
36 = L x W
36= 6 x 6
^ Find the square root of 36
The answer would be 6 according to me!
Hope that helps!!
Answer:
-1.596
Step-by-step explanation:
4^(x + 3) = 7
log4 both sides
log4[4^(x + 3)] = log4(7)
(x + 3) × log4(4) = lg7/lg4
x + 3 = 1.403677461
x = -1.596322539
The factored form of this equation is (n+5)(n-5). Hope this helps you.
