The sum of one-fifth of a number and two is five

Veseljchak [2.6K]

Answer:

Step-by-step explanation:

Let us first write an equation where the unknown number is represented with variable x. The sum of a fifth of x and two is five:

$\frac{1}{5} x+2=5$

Great! Let's solve for x by isolating the variable.

$\frac{1}{5}x=3\\x=15$

Therefore, the unknown number is 15.

I hope this helps! Let me know if you have any questions :)

What is the value for the missing angle ??

allsm [11]

Answer: 9 inches.
Do the pythagorean theorem to find your answer.
Formula: a^2 + b^2 = c2
12 = b
15 = c
a^2 + 12^2 = 15^2
Simplify the equation
a^2 + 144 = 225
Subtract 144 on both sides.
a^2 = 81
Square root of 81 is 9.
