First, insert the given numbers into the equation. (a = 10 , c = 4)
a + 9c becomes 10 + (9 × 4)
Use PEMDAS (parenthesis, exponents, multiplication, division, addition, & subtraction) to solve the equation.
First, do the multiplication inside of the parenthesis.
9 × 4 = 36
Now do the addition.
10 + 36 = 46
Answer:
10 + (9 × 4) = 46
hope this helps :)
