9. 3x-6=4-2x
First, add 2x to both sides.
5x-6=4
Add 6 to both sides.
5x=10
Divide both sides by 5.
x=2
10. 3x+x=2x+6
Combine like terms.
4x=2x+6
Subtract 2x from both sides.
2x=6
Divide both sides by 2.
x=3
11. 6x=2+x+8
Combine like terms.
6x=10+x
Subtract x from both sides.
5x=10
Divide both sides by 5.
x=2
12. 6x+2-2x=x+8
Combine like terms.
4x+2=x+8
Subtract x from both sides.
3x+2=8
Subtract 2 from both sides.
3x=6
Divide both sides by 3.
x=2
I hope this helps :)
9) 3x-6 = 4-2x
add 6 to each side:
3x = 10-2x
Add 2x to each side:
5x = 10
Divide both sides by 5:
x = 10/5
x = 2
10) 3x +x = 2x +6
combine like terms on the left side:
4x = 2x +6
subtract 2x from each side:
2x = 6
Divide both sides by 2:
x = 6/2
x =3
11) 6x = 2 + x +8
Combine like terms on the right side:
6x = x +10
Subtract 1x from each side:
5x = 10
Divide both sides by 5:
x = 10/5
x = 2
12) 6x+2-2x = x +8
Combine like terms on the left side:
4x +2 = x +8
Subtract 2 from each side:
4x = x +6
Subtract 1x from each side:
3x = 6
Divide both sides by 3:
x = 6/3
x = 2

Answer:
You should solve it using system. because we have two unknown values here.
the first equation should be
8y + 17 = 180
the second
17 + 7x = 180
Answer:

Step-by-step explanation:
step 1
Find the circumference of the circle
The circumference is equal to

we have

substitute the values

step 2
Remember that
360 degrees subtends the arc of length
(circumference)
so
by proportion
Find the measure of θ by an arc of length 5 m
assume 

By looking at it, I can tell the second expression is greater due to a a large postive number that's being added to it. Let's solve.
-12+6=-6-4=-10
-34-3=-37+39=2
So, -34-3+39 is greater.
T=i/pr
t=536.25/(2600*0.025)
t=8.25 years
144^(3/2) = √(144^3) = 1,728
