Answer:
Equation:
Step-by-step explanation:
3y = x + 15
y + 3x = 4
To get the y-value Subtract 3x from both sides.
y = -3x + 4
Then substitute;
3(-3x + 4) = x + 15
Distribute: -9x + 12 = x + 15
Subtract x from both sides
-10x + 12 = 15
Subtract 12 from both sides
-10x = 3
Divide both sides by -10
x = 3/-10
Then to get the value of y;
y = -3(3/-10) + 4
Answer: $0.24
Step-by-step explanation:
9.5 inches --> $2.28
1 inch--->X
now cross multiply it and get,
9.5X = 2.28*1
X = 2.28/9.5
so its $0.24 per inch
1000+1000=2000-2000=0 the answer is 0
