Answer:
Multiply a fraction by its reciprocal to show that their product is always 1
Step-by-step explanation:
Answer:The method of substitution involves three steps: Solve one equation for one of the variables. Substitute (plug-in) this expression into the other equation and solve. Resubstitute the value into the original equation to find the corresponding variable.
Step-by-step explanation:
First you set and equation for length which is three times width
l=3w
The substitute in the perimeter, p, into the equation for perimeter which is p=2l+2w
88=2l+2w
Then substitute in length, l, with the equation previously created: l=3w
88=2(3w)+2w
Multiply 2 and 3w
88=6w+2w
Combine like terms: 6w+2w
88=8w
Divide to get the value for w
w=11
Since you figure the value for w, 11, you can plug it into the equation for length which is l=3w
l=3(11)
When you do you get
l=33
So the length is 33 and the width is 11

You could do 6+6+6+6+6+6+6 That's what the distributive property can be used to help you and We 6×7
