Answer:
i believe the answer is A
Step-by-step explanation:
Answer:
x=0
y=6
Step-by-step explanation:
3y- 12x = 18
2y-8x= 12
rearrange the equation
2y-8x=12
add 8x to both sides
2y=8x+12
divide both sides by 2
y=4x+6
now substitute it into 3y-12x=18
3(4x+6)-12x=18
simplify
12x+18-12x=18
simplify
18=18
x=0
substitute to find y
2y-8(0)=12
2y=12
y=6
Recheck:
3(6)-12(0)=18
18=18
2(6)-8(0)=12
12=12
It is: 79.95 + (79.95 * 15%)
= 79.95 + (79.95 * 0.15)
= 79.95 + 11.9925
= 91.9425
Hope this helps!
