Solve for x:
x + 11 - 2 = 18
x = 18 - 11 + 2
x = 9

Solve for x:
3x + 2 = 23
3x = 23 - 2
3x = 21 / 3
x = 7
Is 1,623 divisible by 3?
(add the digits, check if the sum is divisible by 3)
1+6+2+3 = 12 / 3 = 4, YES!

Describe the trends for the wildlife population of bears, whales, and dolphins. If the trend continues, about how many bears should we expect to see in the year 2023?
Bears - population is increasing
Whales - population dips up and down but overall is stable
Dolphins - going extinct?!
We should expect around 200 bears.
Calculate the area and perimeter of a rectangle that is 5 meters long and 6 meters wide.
Area = 5 x 6
= 30m2
Perimeter = 5+5+6+6
= 22m
Solve for x:
-5x + 7x = 10
2x = 10/2
x = 5
Use exponent laws to simplify and solve:
103 x 106 x 102
3+6+2 = 11
100,000,000,000
What is the greatest common factor of 24 and 40?
24: 1 2 3 4 6 8 12 24

GCF = 8
Describe viewership of the TV channel in August and compare it to viewership in May?
August - Viewership at 9:30 suddenly dipped, viewership at 11pm increased dramatically, viewership at 6pm dipped a bit but stayed stable, and the viewership at 1pm stayed low, but stable.
May - Viewership at 6pm and 9:30pm were much more popular, viewership at 1pm was the same, viewership at 11pm just started and was very low
I have a rectangle that is 3 meters long and 4 meters wide. Name the dimensions of 2 other rectangles that would have the same area.
6 x 2
1 x 12
Solve for x:
x + 3 - (3 x 2)2 = 50
x + 3 - (6)2 = 50
x + 3 - 36 = 50
x = 50 - 3 + 36
x = 83
8 + (2 x 5) x 34 ÷ 9 = ?
= 8 + (10) x 81 ÷ 9
= 8 + 10 x 9
= 8 + 90
= 98
Reduce the fraction to lowest terms.
12/16
(Find the GCF, then divide the numerator and denominator by the GCF)
GCF = 4
12/16 = 3/4
There is an outlier on this scatterplot. What continent does it belong to and what does it mean?
*gdpPercap = GDP per capita (how much money a household in a country earns)
*lifeExp = life expectancy (how old people in that country expect to get)
(100,000 , 60) is the outlier. It means that Asian countries with a GDP per capita of $100,000 also have populations of people who expect to live to around 60 years old.
Use the formula to calculate the surface of a rectangular prism that is 5 meters long, 3 meters high, and 4 meters wide.
Formula:
SA = 2([l x w] + [l x h] + [w + h]
SA = 2([5 x 4] + [5 x 3] + [4 x 3])
= 2(20 + 15 + 12)
= 2(47)
= 94 m2
Solve for x:
2x2 + 6 = 38
2x2 = 38 - 6
2x2 = 32 / 2
x2 = 16
x = 4
