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.
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
