Answer:

z=3

Step-by-step explanation:

2(2z -4)=4

Divide by 2

2/2(2z -4)=4/2

2z-4 = 2

Add 4 to each side

2z-4+4 = 2+4

2z = 6

Divide by 2

2z/2 = 6/2

z=3

6 is 55% of what number? Round answer to nearest tenth (1 number after decimal)
Arada [10]

Answer:

10.9

Step-by-step explanation:

Formula = Number x 100

Percent = 6 x 100

55 = 10.91

Following shows the steps on how to derive this formula

Step 1: If 55% of a number is 6, then what is 100% of that number? Setup the equation.

6

55% = Y

100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

55Y = 6 x 100

55Y = 600

Y = 600

100 = 10.91
