Answer:
Divide by 2
Then subtract 4
Step-by-step explanation:
Let y = 2(x+4)
Exchange x and y
x = 2(y+4)
We want to solve for y
Divide each side by 2
x/2 = y+4
Then subtract 4 from each side
x/2 -4 =y
The inverse is x/2 -4
2/4 reduces to 1/2
3/6 reduces to 1/2
1/2 * 1/2 = 1/4
he used 1/4 yard of string
In order to solve, set up a proportion: 22/126=x/100. Cross multiply: 2200=126x. Divide by 126 on both sides: 17.46%=x
