Answer:
6
Step-by-step explanation:
multiply 50 by .12 to get 6
So to set up the equation we have:
<span><span><span>4M</span><span>4+M</span></span>=<span>127</span></span>
<span>28M=12(4+M)</span>
<span>28M=48+12M</span>
<span>28K−12M=48</span>
<span>(28−12)M=48</span>
<span>16K=48</span>
<span>M=<span>4816</span></span>
<span>M=3</span>
So Marna can clean the chimney alone in 3 hours
Mr. Lewis | 100$
Glue = 1.50$ (x40)
Box = 0.89$ (x40)
1.50 x 40 = 60$
0.89 x 40 = 35,6$
Total spend (95,6$)
100 - 95,6 = 4,4$
Answer: 4,4$
Answer:
- 8
Step-by-step explanation:
Given
(4 +4 x²)(3x² - 5)
Each term in the second factor is multiplied by each term in the first factor, that is
4(3x² - 5) + 4x²(3x² - 5) ← distribute parenthesis
= 12x² - 20 + 12
- 20x² ← collect like terms
= 12 - 8x² - 20
with coefficient of x² term being - 8
