If she is setting up a proportion to find the percent, the value of m would be any variable and the value of n would be 100.  When she solves the problem, m=65%.

13/20 is part out of whole.  The rest of the proportion will be "percent out of 100"; since we don't initially know the percent, we use a variable.  Thus we have

13/20 = m/100

Cross multiply:
20*x = 13*100
20x = 1300

Divide both sides by 20:
20x/20 = 1300/20
x = 65

5 times a number increased
Brrunno [24]

Answer:

18

Step-by-step explanation:

Let's make this information into an equation.

We'll use 'x' whenever the problem says "a number".

Equation:

5x + 18 = 36 + 4x

How did I get to this equation?

  • 5 times a number means 5 multiplied by x
  • increased by 18 means to add 18
  • is the same as means equals
  • 36 more than means to add 36
  • 4 times the number means 4 multiplied by x

Now, let's solve.

Solve:

5x + 18 = 36 + 4x

Subtract 18 on both sides:

5x + 18 = 36 + 4x

     -18     -18

5x = 18 + 4x

Subtract 4x on both sides:

5x = 18 + 4x

-4x        -4x

x = 18

Therefore, "the number" is 18.

In the above figure, m AOC=26 and m BOD= (2x+39). If AOC and BOD are vertical angles whats the value if x?
Reika [66]

If AOC and BOD are vertical angles, the value of x is x = -6.5

<h3>How to determine the value of x?</h3>

The angles are given as:

m AOC = 26

m BOD = (2x+39).

From the question, we have

AOC and BOD are vertical angles

Vertical angles are equal.

So, we have:

AOC = BOD

Substitute the known values in the above equation

2x + 39 = 26

Subtract 39 from both sides

2x = -13

Divide bot sides by 2

x = -6.5

Hence, if AOC and BOD are vertical angles, the value of x is x = -6.5
