to get GCF find what divide into both numbers
2 | 8 16
4 | 4 8
1 2
now multiply the numbers on the side 2 x 4 = 8 that's the GCF
To solve this you must use the rules of PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction)
There are no parentheses or exponents in this expression, so to the next step (Multiplication/Division)
Now comes the problematic part, in which many people get confused. Although in the PEMDAS order it shows multiplication before division, you must remember that multiplication and division are "paired." This means that you will apply these two operations in the order they come first in the expression as you read it from left to right.
In this case that would be division first then multiplication.
NOTE: This rule also applies when you are dealing with addition and subtraction in the same expression
50÷5+3×4÷2-1
50 ÷ 5 = 10
10 + 3 × 4 ÷ 2 - 1
3 × 4 = 12
10 + 12 ÷ 2 - 1
12 ÷ 2 = 6
10 + 6 - 1
Addition/Subtraction
10 + 6 - 1
10 + 6 = 16
16 - 1
15

Answer:
simultaneous linear equations
Step-by-step explanation:
y=7x+3
y=x-3
If you have the two other angle measures:
You can add the angles together and subtract them from 180.
Example:
Angle 1: 90
Angle 2: 45
Angle 3: ?
90 + 45 = 135
180 - 135 = 45
Angle 3 is 45 degrees.
This is because all three angles of a triangle need to be equal to 180 when added up.
Answer:
5.5 miles over 2 hours--> 5.5/2= 2.75 miles per hour was his average walking speed. 5.5 miles over 2.5 hours --> 5.5/2.5= 2.2 miles per hour on the return trip meaning that his average speed was (2.75-2.2= 0.55) 0.55 miles per hour lower on the return trip
Step-by-step explanation:
I hope this helps you :)
