"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.

Find the value of x.
Irina-Kira [14]
The 2 angles are complementary angles and need to equal 90 degrees.

Making an equation we have:

4x-10 + x = 90 degrees

Add like tems:
4x +x = 5x

Now we have:
5x-10 = 90

Add 10 to both sides:

5x = 100

Divide both sides by 5:

x = 100/5

X = 20

What is an equation of the line that passes through the point (3, -8) and has slope -2?
BabaBlast [244]

Answer:

Step-by-step explanation:

slope of -2 means the slope is -2/1

from (3, - 8) you can find the y intercept by going backwords until x = 0

(2,-6)

(1,-4)

(0,-2)

so the y intercept is -2

y = -2x - 2

If 5.9% of female population was diagnosed with diabetes what percentage was not diagnosed
svet-max [94.6K]

Answer: 94,1%

Step-by-step explanation:

The probability of people with diabetes:

P (Diabetes) = P(diagnosed women) + P (undiagnosed women)

1= 0,059 + P (undiagnosed women)

P (undiagnosed women)= 1-0,059= 0,941--> 0,941x100= 94,1%
