Take note that they spent $18 afterwards having $28 on the card so they're spending money off the card so...
x-18=28
would be the equation for this and to solve do the following.
First add 18 to both sides making the equation.
x=46
Answer:
x=25 degrees and the angles are vertical (opposite each other)
Step-by-step explanation:
(4x-25)=75
4x=100
x=25
G(-1/4)>=17/(-1/4)
g>=-68
8x=64
8x/8=64/8
x=8
