Answer:
Step-by-step explanation:
we know that
The formula for the perimeter of a rectangle is equal to
where
l is the length
w is the width
Solve for l
That means ----> Isolate the variable l
Divide by 2 both sides
Simplify right side
Subtract w both sides
Simplify right side
Rewrite
Answer:Solve P = 2l + 2w for w.
The first step is to isolate the variable term, 2w.

Answer:
3 times
Step-by-step explanation:
Jess needs 3/4 cup of sugar. Note that 3/4 is the same as 1/4 + 1/4 + 1/4, which in turn is the same as 3(1/4).
Jess will need to fill her 1/4-cup measure 3 times to end up with 3/4 cup of sugar in the banana bread batter.
Answer:
Step-by-step explanation:
The figure is composed of 3 Right triangles. To find the values of the variables x and y we use the Pythagorean theorem to propose one equation.
Now we solve for x
Let's call z at the angle opposite to y
Then we have that:
Where
Now we use this angle to find the length y
Where in this case
