Let's Try
In your notes write the algebraic expression described by these statements
1) the quotient of 96 and the square root of 9
96/√(9) = 96/3
2) twice 6
2*6
3) 10 less than 7 cubed
73 ‐ 10
4) the quantity of 9 times 5 decreased by 7
(9*5) ‐ 7
5) 10 increased by 8
10 + 8
6) 7 squared less 4
72 ‐ 4
7) the product of 4 and 5 equals 10 times a number
4 * 5 = 10 * x
