She will need to cut 26.6 haircuts a month a location A to break even (1200/45 = 26.6) so roughly 27 haircuts to make a profit
She will need to cut 30 haircuts at location B to break even (1800/60 = 30) and 31 hair cuts to see a profit.
She will need to cut 30.67 haircuts at location A and 33 haircuts at location B to make the same profit at either location (Roughly $180).
30.67 x 45 = 1380.15 - 1200 = 180
33 x 60 = 1980 - 1800 = 180
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
The correct answer is 42.
5 • 8 = 40
40 + 2 = 42
Answer:
x = {9, -3}
Step-by-step explanation:
- 2| x-3| - 5 = 7
- 2| x-3| = 12
- | x-3| = 6
- x - 3 = ± 6
- ⇒ x= 3+ 6= 9
- ⇒ x= 3 - 6= -3
Or it can be shown as:
