Answer:
1. 90
2. 150
3. 43
4. 42
5. 85
Explanation:
Just substitute the values given in the numbers provided.
1. 8c + 10c ; c = 5
8(5) + 10(5)
40 + 50 = 90
2. 12bd + 3b ; b = 2 , d = 6
12(2)(6) + 3(2)
12(12) + 6
144 + 6 = 150
3. (4h - 4g) + (5g + 4h) ; h = 5 , g = 3
(4(5) - 4(3)) + (5(3) + 4(5))
(20 - 12) + (15 + 20)
8 + 35 = 43
4. 12a - 3b ; a = 4, b = 2
12(4) - 3(2)
48 - 6 = 42
5. 25xy + 35y ; x = 2 , y = 1
25(2)(1) + 35(1)
25(2) + 35
50 + 35 = 85
