Answer:
x=3, y=8; (3,8)
Step-by-step explanation:
To use the substitution method, first solve for a variable.
2x+y=14
2x+y(-2x)=14(-2x)
y=14-2x
Now substitute y in the other equation with 14-2x
5x-2(14-2x)= - 1
Simplify by multiplying inside the parenthesis.
5x-28+4x= - 1
Combine the x values
9x-28= - 1
9x=27
x=3
Now substitute the x value in to solve for y
2(3)+y=14
6+y=14
y=8
Answer:
203.20 millimeters
Step-by-step explanation:
StartFraction 8 inches Over question mark millimeters EndFraction = StartFraction 40 inches Over 1,016 millimeters
8 inches / ? Millimeters = 40 inches / 1,016 millimeters
8 × 1,016 = ? × 40
8,128 = 40?
Divide both sides by 40
? = 8,128 / 40
= 203.20
? = 203.20 millimeters
There are 203.20 millimeters in 8 inches
