1. Evaluate the following expression:
stira [4]

Answer:

1. 37, 2. 1 2/5

Step-by-step explanation:

For Question 1:

Step 1: Replace the x values

x= 3, y=5

Now you get...

9x + 2y --->  (9 x 3) + (2 x 5)    

(Remember, if an x value is beside a number, and it is replaced, that replaced number is to be multiplied with the number the previous x value was.)

Parentheses first, Multiplication second, Addition third (look at PEMDAS below :) )

Step 2: Multiply and Add

(9 x 3) + (2 x 5)

27 + 10

37

For Question 2:

Step 1: Replace the x and y values

m = 1, p = 5

Now your equation should look like this:

m + p ÷ 5 ---> 1 + 2 ÷ 5

Now, which one to do first? Use the PEMDAS strategy

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

You have to do it from top to bottom

Division comes first, which means, you have to divide first, then add:

2 ÷ 5 = 2/5

2/5 + 1 = 1 2/5

Hope this helps :)
