Write an Equation
The sum of a number 'p' and 12 is 25
Is 5 a solution to 4x = 9?
NAY
4(5) does not = 9
6x = 42
6x = 42
/6 /6
x = 7
True or False:
In a graph, the x-axis runs horizontally (left to right)
True
60 is the product of a number 's' and 5
60 = 5s
Is 12 a solution to: 5 + x = 7
NAY
5+12 does not = 7
n + 4 + 2 = 17
n + 6 = 17
-6 -6
n = 11
True or False
When asked to graph, you should create the ratio table first.
True
The area of a rectangle is 42 square meters. If the length is 5 meters, then write an equation that can be used to find the width called 'w'.
5w = 42
In science class, you are measure the weather and the temperature is increase 3 degrees every minute during the experiment. The two variables are 'm' for minutes and 'd' for total degrees.
Is 'm' the independent variable?
YAY
r/2.3=5.4
r/2.3=5.4
x2.3 2.3
r = 12.42
Graph the equation y = 3x + 1
Make a table and then graph points:
(0,1) (1,4) (2,7) (3,10) (4,13)
Don't forget to connect points and arrow.
The cafeteria sells the new sparkling ice at $3 per bottle. If they sell 's' sparkline ices, then how much 'd' dollars will they earn?
3s = d
Is (4,3) a solution to: y = x + 1
y = x + 1
3 = 4 + 1
3 = 5...NAY
They had x and y reversed :)
2/3x=32
(3/2)2/3x=32(3/2)
x=48
In tech class, your racer moved at 2 feet per second. Complete a table and graph the relationship between 'f' total feet and 's' seconds.
(0,0) (1,2) (2,4) (3,6) (4,8)
A cell phone plan costs $65 to join. Then, you also pay $25 per month. Write an equation that shows how much 'd' dollars you will be charged after 'm' months.
65 + 25m = d
Is 4/5 a solution to:
5/6x=2/3
5/6x=2/3
5/6(4/5)=2/3
Cross Simplify
2/3=2/3
YAY
4(x+3)=22
4x+12=22
-12 -12
4x = 10
/4 /4
x = 2.5
A new stock is steadily increasing at a rate determined by the equation 8m=d where 'm' stands for months and 'd' for total dollars. Use your equation to determine after how many months will the stock be worth $46
8m = d
8m = 46
/8 /8
m = 5.75 months or 5 3/4 months
