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
Hope this helped!

Answer:
Population: all of the students at the town's high school
Sample Examples:
- An equal fraction of students from each grade.
- Every 5th student arriving at the school at a certain day.
Step-by-step explanation:
The population of a survey is the group whose data is desired.
If Alan wants to determine the type of art preferred by students at the town's high school, the population of his survey is all of the students at the town's high school.
It might not be realistic to interview every student, which is why samples are used. Samples must be designed in a way that represents the whole population without bias. One way to do it would be to survey an equal fraction of students from each grade. Another alternative, is to randomly survey every 5th student arriving at the school at a certain day.
Answer:
43b. (-1, 2)
43a. (1, -3)
36b. Yes: (0,9)
Step-by-step explanation:
<u>43b</u>. x+y=1
-x+y=3
----------------------
2y=4 > y=2
2+x=1 > x=-1
check:
2(-1)+2=0
0=0
<u>43a</u>. can you figure this one out by yourself and then check it? If you can't I will show my work. The answer is above. :)
<u>36b</u>. y-(0)^2=9
y=9
