Answer:
5.5 hours
Step-by-step explanation:
Since every house has an initial charge of $50, we can begin with that
($50)
Then, let's define h as the number of hours. We know every hour is $70, although the hours is yet unknown so that can be
($70 * h) or simply ($70h)
Now, we know the total should end up to be $435, so after PEMDAS the equation will be
($70h + $50 = $435).
We subtract 50 from both sides so now we have $70h = $385.
Now we divide both sides by 70, giving us h = 5.5. Hope it helped!
Answer:
45:63
Step-by-step explanation:
7+5=12
12u-->108
1u--> 9
5u-->45
7u-->63
MA/MN = MB/BP
MA = 46.2 -14
MA=32.2
so
MA/MN = MB/BP
32.2/46.2=x/72.6
46.2x = 72.6 * 32.2
46.2x = 2337.72
x = 2337.72 / 46.2
x = 50.6

V = l w h <span>V = s3</span>
V = (5 mm)(5 mm)(5 mm) V = (5 mm)3
<span>V = 125 mm3</span> <span>V = 125 mm<span>3</span></span>
Step-by-step explanation:
y-5=1/2(x+8) =
2(y-5)=x+8
2y-10=x+8
2y=x+18
2y-x-18=0
