2x^2 + 25x + 50 not sure about the steps
The mathematical expression of the given above is 4/y^-3 where only the denominator is raised to exponent -3. Remember that the expression x^-n may also be expressed as 1/x^n. Thus, for the given, transfer the y^-3 of the denominator to the numerator to give the final answer of 4y³.
$1.60 is the answer you divided 5.20 divided by the two items and you get 2.6 which you subtract the 1 dollar and get 1.6
5 + 5 + 5 + 5 + 5 + 5 = 30 (6 bills)
1 + 1 + 1 + 1 + 1 = 5 (5 bills)
30 + 5 = 35 (11 bills)
