Write an equation that represents the hanger diagram
7 = 3x + 1
Write an equation to represent the area of the rectangle below:
20s = ?
Write an equation that shows the relationship
15% of 160 is x
15/100 * 160 = x
When x = 3 is the equation true? Explain your reasoning
x-3 = 0
Yes, when x = 3
3-3=0.
How many 6th graders are track athletes if the team has 90 track athletes? Explain your reasoning.
18 6th Graders are Track Athletes
Write an equation for the tape diagram
3z + 22 = 49
Write an expression for the sum of the areas of the two rectangles.
5(x+8)
5x + 40
5x + 5 * 8
Write an equation that shows the relationship
20% of y is 42
20/100 * y = 42
When x = 3 is the equation true? Explain your reasoning
1-x = 3
No as this would get us a negative value, so it would not be equal to 3

Write an equation that represents the area of the rectangle
6(4p)
24p
6p+6p+6p+6p
15% of 35 is p. Find the value of p.
p = 5.25
When x = 3 is the equation true? Explain your reasoning
10 - x = 8
Not True
10 - 3 = 7

m(6+8)
6m+8m
14m
Area = 28 units squared
25% of w is 10. Find the value of w.
w = 40
When x = 3 is the equation true? Explain your reasoning
1/2x = 1 1/2
True as 3/2 = 1 1/2
At Jane Addams Middle School, 30% of the track athletes are in 7th grade. There are 12 athletes in 7th grade on the track team.
If the track team has x athletes, write an expression for the number of 7th graders in terms of x.
30/100 * x = 12
DAILY DOUBLE!!!!!
Write an equation for the tape diagram. Find a solution.
3(x+4) = 45
x = 11
Find the area of the rectangle when r=1/2
Area = 1 1/2 units squared or 3/2 units squared
40% of m is 90. Find the value of m.
40/100 * m = 90
90 รท 0.4 = 225
When x = 3 is the equation true? Explain your reasoning
x4 = 81
True as
x*x*x*x = 3*3*3*3
3*3*3*3=81
At Jane Addams Middle School, 30% of the track athletes are in 7th grade. There are 12 athletes in 7th grade on the track team.
If the track team has x athletes, write an expression for the number of 7th graders in terms of x. Find the value of x.
30/100 * x = 12
12 * 10/3 = 120/3
120/3 = 40
