Step-by-step explanation:
x = number of hours A
y = number of hours B
x + y = 23
5.7x + 7.1y = 143.7
from the first equation we get
x = 23 - y
this we use in the second
5.7×(23 - y) + 7.1y = 143.7
131.1 - 5.7y + 7.1y = 143.7
1.4y = 12.6
y = 12.6/1.4 = 9
x = 23 - y = 23 - 9 = 14
she worked 14 hours on job A and 9 hours on job B.
Hi there!
If Jeremy walked 6/8 of the way to school and ran the rest we know that Jeremy ran 2/8 of the way. We can simplify this further to get to our simplest form.
6/8 ---> 3/4 Simplified.
So your answer is Jeremy walked 3/4 of the way.
L=2W+2
W=(L-2)/2
A=LW, using W from above makes this
A=L(L-2)/2
2A=L^2-2L
L^2-2L-2A=0, given A=84
L^2-2L-168=0
(L-14)(L+12)=0, since L>0
L=14
The length of the rug is 14 ft
(W=(L-2)/2=6 ft)
Answer:
The volume would be 12 inches.
Step-by-step explanation:
Volume is LxWxH
for the lower box, I did
4x2x1=8
For the top half
2x2x1=4
Then i added them together
8+4= 12
