Hi there! :)

The answer is D. 25% of 180 is 45.

Step-by-step explanation:

Let's replace "what percent" with the letter "x" because it's what we are looking for.

The word "of" is the same thing as a multiplication sign, which means that the sentence "What percent of 180 is 45?" can turn into "x times 180 is 45".

The word "is" is the same thing as an equation sign, wich means that you can write this as an equation:

x × 180 = 45

180x = 45

Now all you have to do is solve this equation by isolating "x" to find your

180x = 45

Divide each side of the equation by 180 → 45 ÷ 180 = 0.25

x = 0.25

0.25 = 25 ÷ 100 = 25%

There you go! I really hope this helped, if there's anything just let me know! :)

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
