Bill has a certain amount of money in his piggy bank. After helping his mom clean the house, his mom gave him another $10, which he added to his piggy bank. This expression could be written showing how much money Bill has in his piggy bank now. (use x as your variable).
x + 10?
(or 10 + x)
Judy made 24 cookies to give as presents for 3 friends. She wants to give each friend the same number of cookies. If n represents the number of cookies she will give each friend, this equation could be written to find out how many cookies each friend will get.
24 ÷ 3 = n
or 3n = 24
My dog went to the vet two weeks ago and weighed ‘p’ pounds. The vet told me that he had to lose weight. During the next two weeks, my dog lost 10 pounds. This expression could be written to show how much my dog weighs now.
p – 10 ?
Last week, Tom earned ‘n’ dollars doing chores around the house. This week he earned $12 doing chores. After both weeks, he had earned a total of $20. This equation could be written to find how much money he earned during the first week.
n + 12 = 20
or 20 – 12 = n?
Mr. Linden’s son is ‘x’ years old. Mr. Linden is 30 years older than his son. Mr. Linden is 55 years old. This equation could be written to find out how old Mr. Linden’s son is.
x + 30 = 55 or 30 + x = 55
55 – 30 = x or 55 – x = 30
(any of the above equations will work!)

Nick measured an angle using a protractor and found out it measured 35 degrees. This is the name for the type of angle he measured.
What is an acute angle?
This point is in the exterior of angle EDC.
Of the following measurements , this is the best estimate for the pictured angle.
Of the following, this is a proper name for the pictured angle.
This is the name of an obtuse angle in the picture to the left.
Angle ACD or
Each angle at the base of the triangle is 70 degrees. This is the number of degrees of the top angle of the triangle.
40 degrees ?
Explanation: The sum of all the angles in any triangle is 180 degrees. The bottom two angles total 140 degrees, so the top angle must be 40 degrees.
This line is parallel to CD
AB or BA?
This formula could be used to determine the perimeter of the above shape.
P = 2 x (8 + 4)P = 8 + 4 P = 8 x 4
P = 2 x (8 + 4)?
The shape pictured to the left is known as a regular dodecagon, which is a twelve sided shape, where all 12 sides are the same length. If each side is 10 cm. long, this is the perimeter of the shape.
The width of the rectangle pictured below is n units long. The length of the rectangle is 4 times the width of the rectangle. If n = 2 inches, this is the perimeter of the rectangle.
What is 20 inches?
Explanation: According to the information, the shorter side is 2 inches long. Since the longer side is 4 times the shorter side, the longer side must be 8 inches long. If you add up two shorter sides (2 + 2) and 2 longer sides (8 + 8), you will get an answer of 20 inches.
