Uggh!! help pls last question

The answer is 46.

Step-by-step explanation:

You have to substitute the value of a and c into the expression :

Let a = 10,

Let c = 4,

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

10 + (9 × 4) = 46

hope this helps :)
