Answer:
Simplifying
3x + 77 = 4x + 54
Reorder the terms:
77 + 3x = 4x + 54
Reorder the terms:
77 + 3x = 54 + 4x
Solving
77 + 3x = 54 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
77 + 3x + -4x = 54 + 4x + -4x
Combine like terms: 3x + -4x = -1x
77 + -1x = 54 + 4x + -4x
Combine like terms: 4x + -4x = 0
77 + -1x = 54 + 0
77 + -1x = 54
Add '-77' to each side of the equation.
77 + -77 + -1x = 54 + -77
Combine like terms: 77 + -77 = 0
0 + -1x = 54 + -77
-1x = 54 + -77
Combine like terms: 54 + -77 = -23
-1x = -23
Divide each side by '-1'.
x = 23
Simplifying
x = 23

Answer:
C
Step-by-step explanation:
Keep a consistent ratio of 4:2, and we need a total of 36 glasses of punch.
So if the ratio 4:2 is a total of 6, then we would need 6 times the amount because 6*6 is 36. So 4 and 2 * 6 or 6 (4+2) = 24+12. So the answer is C.
Hope this helps in some way.
Answer:
Answer 7
Step-by-step explanation:
This depends on setting up a proportion
5:45 :: 3: 3 + 2x + 10
You can reduce 5 / 45
5/45 = 1/9
1:9 :: 3:3 + 2x + 10
1:9 :: 3: 2x + 13
1/9 = 3/(2x + 13) Cross Multiply
2x + 13 = 3*9
2x + 13 = 27 Subtract 13
2x + 13 - 13 = 27 - 13
2x = 14 Divide by 2
2x/2 = 14/2 Divide
x = 7
