Answer:
Zack = x
Tony = x + 6
x + x + 6 = 42
2x + 6 = 42
2x = 36
x = 18
So,
Zack = x = 18
Tony = x + 6 = 18 + 6 = 24
Answer:
Y= -1/3x +2.5
step-by-step explanation:
first I reconfigured the given equation: x+3y=15
-x+x+3y=15 -x Subtracted x from both sides
3y=15-x Simplify
3y/3=15-x/3 Divide both sides by 3
y=-1/3x+3 Simplify
I turned it into y=-1/3x+5
then I translated the line up and down to find what point crossed (6,1)
The proper value for B in y=mx+b was 2.5
Try using Desmos online calculator it really helps
Hope this helped :)
