uggh!! help pls last question

Answer:
The answer is 46.
Step-by-step explanation:
You have to substitute the value of a and c into the expression :
[tex]a + 9c[/tex]
Let a = 10,
Let c = 4,
[tex]10 + 9(4)[/tex]
[tex] = 10 + 36[/tex]
[tex] = 46[/tex]
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 :)
