"Please Excuse My Dear Aunt Sally<span>". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".
</span><span> we follow PEDMAS simply because that's the accepted convention, but we have the convention because it fits common cases well and makes mathematical expressions easier to read.

I don't know exactly what answer you're looking for but that's what I got. This shouldn't have been hard to pick up on in class lol.

What is PEMDAS you ask right?well PEMDAS is a thing you use to solve equations with either parentesis,exponets,when adding,subtracting,multiplying,and dividing.for example, (4+9)20÷5.the first thing that you'll do is what is in the parentesis.4+9=13.then,20÷5=4.finally since there isnt a sign on what to do with 13 &4 you just multiply.4×13=52.we use PEMDAS so it can add order when solving a problem like the example.

kotegsom [21]

Answer:

(5,2)

Step-by-step explanation:

you need to go two half way from the farthest point from the left to the right so that would be from 2 to 8 which is a distance of 6 so you go halfway over and that puts you at 5 then you find the distance from the lowest point to the highest point which goes from -2 to 6 with a distance of 8 so that means you go up for which puts you at 2 which means the center of the triangle is at the point (5, 2)

Need some help, Thank you!!! ^^

Given:

3b+8\geq 14

To find:

The steps to solving the given inequality.

Solution:

We have,

3b+8\geq 14

Subtract 8 from both sides.

3b+8-8\geq 14-8

3b\geq 6

Divide both sides by 3.

\dfrac{3b}{3}\geq \dfrac{6}{3}

b\geq 2

Two steps are:

1. Subtract 8 from both sides of the inequality.

2. Divide both sides of the inequality by 3.

Therefore, the correct option is A.
