Answer:
15:20
Step-by-step explanation:
We can simplify the ratio to 3:4
after doing that we can multiply both sides by 5 giving us
15:20 as our answer
Or you can cross multiply
9 : 12 = 15 : x
Now we have 9x = 180
divide both sides by 9 and we get
x=20
which would work giving us the ratio of 9 : 12 = 15 : 20
Answer
x=1/7y+1/7
Step-by-step explanation:
y=7x−1
Step 1: Flip the equation.
7x−1=y
Step 2: Add 1 to both sides.
7x−1+1=y+1
7x=y+1
Step 3: Divide both sides by 7.
7x

Divide the length of the wall by 2 to find the center:
11/2 = 5.5 feet.
Divide the length of the shelf by 2 to find the center of the shelf:
2.5 / 2 = 1.25
Subtract the center of the shelf from the center of the wall:
5.5 - 1.25 = 4.25 feet.
False if there is a negative exponent move it to the other side for the fraction
7.5
Explanation:
11-3.5=
Take 3 away form 11 and then get 8 then subtract.5 and you are left with 7.5
