Unit 4: One Step Equations Review

X + 29 = 82

X – 4.3 = 13

1.2X = 18

X ÷ 8 = 23

The area of a rectangle is 98 sq. mm. If the length of the rectangle is 14 mm, what is the width? Write an equation AND solve. (Area of a rectangle = length · width)

X -74 = 123

X ÷ 0.7 = 1.3

The perimeter of a triangle is 72 inches. One side measures 31 inches, and another side measures 16 inches. What is the length of the third side? Write an equation AND solve.

19.2 = x

807 = 3x

X - 27 = 39

The area of a triangle is 50 sq. cm. The base measures 10 cm. What is the height of the triangle. Write an equation AND solve. (Area of a triangle = ½ · b · h)

0.6x = 3.48

X = 102

X – 23.1 = 6.72

The distance from McClure to the GA Aquarium is 37 miles. You know The Varsity is 8 miles from the GA Aquarium. Write an equation AND solve to find the distance from McClure to The Varsity.

2.52 = 12X

17 years ago Michael Jordan broke the record for the most consecutive games played. If Mr. Jordan is 42 today, how old was he when he broke the record? Write an equation AND solve.

Answers 1.Title slide 2.X = 53 3.X = X = ¼ 5.X = 15 6.X = x = 98  X= 7mm 8.X = 9.X = x = 0.91

Answers Continued 11. X = = x OR 72 = 47 + x  x = 25 in. 13. X = X = ⅓ 15. X = X = = ½ · 10 · h OR 50 = 5h  h = 10 cm. 18. X = X = X = 370

Answers Continued 21. X = 22. X = X + 8 = 37  x = 29 miles 24. X = 25. X = X = 27. X + 17 = 42  x = 25 years old
