The total amount of money that Jenny and Susan spent is the sum of the money spent for the games and pizza. That is,
T = $93 + $6 = $99
We let x be the amount that Susan has. With this representation, the amount of money that Jenny has is x + 17. The equation that would represent this situation is,
x + 17 + x = 99
The value of x from the equation is 42.
ANSWER: $42.
Answer:
Step-by-step explanation:
We have, 120% × x = 36
or,
120
100
× x = 36
Multiplying both sides by 100 and dividing both sides by 120,
we have x = 36 ×
100
120
x = 30

Answer:
3.5x
Step-by-step explanation:
Put into numbers, [4*x+(3x)]*1/2. You cant completely solve for x in this, as we would need an answer with no variable. But, 4*x=4x, and 4x+3x=7x because we would need to combine like terms. But you still need to cut it in half. Half of 7x is 3.5x, so there ya go!
<span>Simplifying
5x + 3 = 10x + -17
Reorder the terms:
3 + 5x = 10x + -17
Reorder the terms:
3 + 5x = -17 + 10x
Solving
3 + 5x = -17 + 10x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10x' to each side of the equation.
3 + 5x + -10x = -17 + 10x + -10x
Combine like terms: 5x + -10x = -5x
3 + -5x = -17 + 10x + -10x
Combine like terms: 10x + -10x = 0
3 + -5x = -17 + 0
3 + -5x = -17
Add '-3' to each side of the equation.
3 + -3 + -5x = -17 + -3
Combine like terms: 3 + -3 = 0
0 + -5x = -17 + -3
-5x = -17 + -3
Combine like terms: -17 + -3 = -20
-5x = -20
Divide each side by '-5'.
x = 4
Simplifying
x = 4</span>
