A: Solve for r:
6 r + 6 r - 1 = 11
Grouping like terms, 6 r + 6 r - 1 = (6 r + 6 r) - 1:
(6 r + 6 r) - 1 = 11
6 r + 6 r = 12 r:
12 r - 1 = 11
Add 1 to both sides:
12 r + (1 - 1) = 1 + 11
1 - 1 = 0:
12 r = 11 + 1
11 + 1 = 12:
12 r = 12
Divide both sides of 12 r = 12 by 12:
(12 r)/12 = 12/12
12/12 = 1:
r = 12/12
12/12 = 1:
Answer: r = 1

B:
Solve for v:
8 = 8 v - 4 (v + 8)
-4 (v + 8) = -4 v - 32:
8 = 8 v + -4 v - 32
Grouping like terms, 8 v - 4 v - 32 = (8 v - 4 v) - 32:
8 = (8 v - 4 v) - 32
8 v - 4 v = 4 v:
8 = 4 v - 32
8 = 4 v - 32 is equivalent to 4 v - 32 = 8:
4 v - 32 = 8
Add 32 to both sides:
4 v + (32 - 32) = 32 + 8
32 - 32 = 0:
4 v = 8 + 32
8 + 32 = 40:
4 v = 40
Divide both sides of 4 v = 40 by 4:
(4 v)/4 = 40/4
4/4 = 1:
v = 40/4
The gcd of 40 and 4 is 4, so 40/4 = (4×10)/(4×1) = 4/4×10 = 10:
Answer: v = 10

C: x+4/3=2
x=(2-4)/3
x=(6/3)-4/3
x=(6-4)/3
x=2/3
Answer/Step-by-step explanation:
I would rather be player A. Player A's graph shows points going up. When lines move up left to right this is a positive graph which means positive points.Player B's graph shows negative points, because this line is moving up right to left. To prove this you can look at the coordinates and it would equal a negative number for player B.
Answer: They will need 18 vans and $1,764.00 to rent the vans out.
Step-by-step explanation:
<em>140/8= 17.5 ( rounded 18)</em>
So in order to fit all students, you'll need 18 vans
<em>98.00* 8= 1,764</em>
<em>So the amount of money you'll need is $1,764.00</em>
