Answer:
1) 100 - 2(35) - 2.50 = x
x= $27.50
2) x * 7 + 345 = 1,740.00
x= (1,740 - 345) / 7
x= $199.29
Answer:
see explanation
Step-by-step explanation:
(9m + 4)² - (9m - 4)² ← expand both factors using FOIL
= 81m² + 72m + 16 - (81m² - 72m + 16) ← distribute parenthesis by - 1
= 81m² + 72m + 16 - 81m² + 72m - 16 ← collect like terms
= 144m
= 72(2m)
which is divisible by 72 for all m

Answer:
x = 34
Step-by-step explanation:
x/3 - 7/3 = 9
Combine like terms
(x-7)/3 = 9
Multiply each side by 3
(x-7)/3 * 3 = 9*3
x-7 = 27
Add 7 to each side
x-7+7 = 27+7
x = 34
