No
Step-by-step explanation:
(12 + 31) × 5 = 215
12 + 31 × 5 = 167
order of operations are the rules that state the sequence in which the multiple operations in an expression should be solved.
Order of Operations :
1. Parentheses
2. Exponents
3. Multiplication and Division
4. Addition and Subtraction
You can show that (y) is proportional to (x) by writing:
![y\propto x](https://tex.z-dn.net/?f=y%5Cpropto%20x)
This would mean that:
![y=kx](https://tex.z-dn.net/?f=y%3Dkx)
Whereby (k) would be the constant of proportionality.
This value can be an element of a real number.
k∈R
What are real numbers?
Integers, rational numbers and irrational numbers.
Example of a graph which would show that 2 objects are proportional:y=2x
Answer:
P = 8w+10
Step-by-step explanation:
To find the dimensions, create an equation for its perimeter and solve. Recall, the perimeter formula for a rectangle is P = 2l+2w. The length is 5 inches shorter than triple its width so 3w-5. And the width is w.
P = 2l+2w
P = 2(3w-5) + 2w
P = 6w-10+2w
P=8w+10
