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 :)

Answer: C
Step-by-step explanation:
Answer: 5
Step-by-step explanation:
Answer:
(a)10 modules per floor
(b)Two different rectangular prism
Step-by-step explanation:
<u>Part A</u>
Number of modules=130
Number of stories=13
Since all of the modules were divided evenly among the number of stories:
Number of module per floor =130÷13=10 modules per floor
There would be 10 modules on each floor.
<u>Part B</u>
Next, we determine how many different rectangular prisms could be made from the number 10 derived above.
Step 1: List the factors of 10
Factors of 10 are: 1,2,5 and 10
Step 2:
Form a product of three terms which equals 10 using the factors derived above. We have two possible combinations:
Therefore, two different rectangular prisms could be made from the number of modules on each floor.
