An algebraic expression is a mathematical statement involving variables and digits. It is evaluated by plugging in the value of the variables.
1. Product of y and 12 is 12y
100 - 12y
Plug in the value of y
100 - 12(7) = 16
2. b(15 + 37) = b(52) = 3(52)
= 156
3. Product of z and 12 is 12z
12z + 27 = 12(5) + 27
= 87
4. 135 ÷ 5c = 135/5(9)
= 3
5. w²(12/4) = 3w²
= 3(10²)
= 300
6. 12d ÷ (25 - 19)
12d/6 = 12(2)/6
= 4
7. 13 + 5x
13 + 5(11)
= 68
