What is eighty percent of seventy.

Mathematics

Answer:

The answer is 5.6

Step-by-step explanation:

1. We assume, that the number 70 is 100% - because it's the output value of the task. 

2. We assume, that x is the value we are looking for. 

3. If 70 is 100%, so we can write it down as 70=100%. 

4. We know, that x is 8% of the output value, so we can write it down as x=8%. 

5. Now we have two simple equations:

1) 70=100%

2) x=8%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

70/x=100%/8%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 8% of 70

70/x=100/8

(70/x)*x=(100/8)*x       - we multiply both sides of the equation by x

70=12.5*x       - we divide both sides of the equation by (12.5) to get x

70/12.5=x 

5.6=x 

x=5.6

now we have: 

8% of 70=5.6

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

4x - 8 = 16

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 8 to both sides:                    4x = 24
  2. Divide 4 on both sides:               x = 6

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                   4(6) - 8 = 16
  2. Multiply:                              24 - 8 = 16
  3. Subtract:                             16 = 16

Here we see that 16 does indeed equal 16.

∴ x = 6 is the solution to the equation.
