Answer:
x = 1/3
Step-by-step explanation:
-12x + 12 = 4 - 15x + 9
Combine like terms
-12x +12 = -15x+13
Add 15x to each side
-12x+12 +15x = -15x+15x+13
3x+12 = 13
Subtract 12 from each side
3x+12-12 = 13-12
3x = 1
Divide by 3
3x/3 = 1/3
x = 1/3
Answer:
<K is 97 degrees
Step-by-step explanation:
4x + 13 = 5x - 8
5x - 4x = x
13 = x - 8
13 + 8 = 21
x = 21
Plug x = 21 in for that.
4(21) + 13 = 97

Answer:D
Step-by-step explanation:
you divide 128 by 2 and then take away the x's and y's
Now, to find how many people are not there, all you have to do is subtract the amount of seats and the people there.
112- 70= 42
Now since there are 7 seats per row and 42 is divisible by 7, you can divide 42 by 7.
42÷7= 6
So, 6 rows were empty.
