Answer:
x = 3
Step-by-step explanation:
1.8 - 3.7x = -4.2x + 0.3
add -4.2x to both sides
1.8 - 0.5x = 0.3
subtract 1.8 from both sides
-0.5x = 0.3 - 1.8
-0.5x = -1.5
divide by -0.5 on both sides
x = 3
GREAT JOB!!!! YOU GOT IT!!! =)
Answer:
1080"
Step-by-step explanation:
12*10= 120
120*9= 1080
(2/3)*(c-18)=7 <em>(Multiply terms on both sides of equation by 3)</em>
2(c-18)=21
2c-36=21
2c=57
c=57/2
c=28.5
Answer:
one of the red things
Step-by-step explanation:
if you subtract two red things from each side, you are left with two red things on one side and two E-tanks on the other. Then you can square root each side to find that one red thing equals one E-tank. Sence we don’t know the value of the red thing, this is as far as we can go
