Answer:
Step-by-step explanation:
1) 6r - 12 + 6r + 11 = 11
Combine like terms
6r + 6r - 12 + 11 = 11
12r - 1 = 11
12r = 11 + 1
12r = 12
r =12/12
r = 1
2) 8m + 5 + 13m - 5 = 42
8m + 13m + 5 - 5 = 42
21m +0 = 42
21m = 42
m = 42/21
m = 2
3) 4x + 5 + 5x + 6 = 29
4x + 5x + 5 + 6 = 29
9x + 11 = 29
9x = 29 - 11
9x = 18
x = 18/9
x = 2
r = 1 m = 2 x = 2
1. 6(1)-12+6(1)+11=11
2. 8(2)+5+13(2)-5=42
3. 4(2)+5(2)+6=29
$22 for popcorn and $8 for pretzels together it would be $30
Is this the answer 95.2185
y + 2007 = 5/29x
5/29 is the slope and 2007 is the y-intercept
