Answer:
Answer: $3.5 per pound
Step-by-step explanation:
Solution: Convert 1 and 1/2 into a decimal which is 1.5 Then divide 5.25 by 1.5 to see how much it is per pound. $3.5 per pound is the answer!
Let's call their parts w,m and s
if will paid 1/3, then m+s=2w (they paid 2/3, which is twice as much as will did)
Now, we know that:
Micah and Sue paid in the ratio 2:3.
this means the 3m=2s
and m=2/3s
Again:
m+s=2w
and we substitute m:
2/3s+s=2w
5/3s=2w// multiply both sides by 3
5s=6w
we also know that s=w+6 (from the last sentence) so we substitute:
5(w+6)=6w
5w+30=6w
30=w
so, Will paid 30, Sue paid 36 (six more than him), Mike paid 24 (24:36 is the same ratio as 2:3, you can check this by dividing both 24 and 36 by 12: you have 2 and 3)
and the total was 30+36+24=90.
Answer:
6) x = 40.5
8) x = 16.5
Step-by-step explanation:
6) 45/x = 20/18
simplify and cross-multiply to get:
45/x = 10/9
10x = 405
x = 40.5
8) 22/8 = x/6
11/4 = x/6
4x = 66
x = 33/2
x = 16.5
Sleeping from 11:00 to 6:20 gets me
7+20/60=7 1/3 hours.
That leaves a sleep deficit of
9 1/4 - 7 1/3 = 9 3/12 - 7 4/12
(8+1) + 3/12-7 4/12=8 (12+3)/12 - 7 4/12
