Answer:
-3=9/5c +32
-3*5c=9/5c*5c+32*5c
-15c=9+160c
-15c -160c =9
c(-15-160)=9
c(-15-160)/(-15-160)=9/(-15-160)
c=9/(-15-160)

Answer:
Step-by-step explanation:
8x -3 = 10x+5
8x-10x = 5+3
-2x =8
x = -4
<span>so use pythagorean theorem where
a^2+b^2=c^2
a and b are legs
c=hypotonuse
in a right triangle
90 degrees=right riangle
so we have 20 and 15
these are the legs
subsitute
20^2+15^2=c^2
400+225=c^2
add
625=c^2
square root both sides
25=c
new pipe=25
how much shorter
old=20+15=35
how much shorter is 25 than 35
35-25=10
answer is 10 miles</span>
Remember
|x| makes x posotive
5|2x-2|+8=18
minus 8 both sides
5|2x-2|=10
divide both sides by 5
|2x-2|=2
assume
2x-2=2 and 2x-2=-2
2x-2=2
add 2
2x=4
divide 2
x=2
2x-2=-2
add 2
2x=0
x=0
x=0 or x=2
