Answer:
152 Chairs
Explanation:
7 rows of 23 chairs: 7 · 23
7 · 23 = 161
Remove 9
161 - 9 = 152
Answer:
b = -2
Step-by-step explanation:
Given expression:
9(b - 4) - 7b = 5(3b -2)
Using distributive properties, open the parentheses;
9b - 36 - 7b = 15b - 10
2b - 36 = 15b -10
collect like terms;
2b - 15b = - 10 + 36
-13b = 26
Divide both sides by -13;
b = -2
