1) Find a number such that three times the number increased by 7 is 52.
Translated: 3x + 7 = 52
x = 2) Find five times a number decreased by 11 is 19.
Translated: 5x - 11 = 19
x = 3) 13 more than four times a number is -91.
Translated: 4x + 13 = -91
x = 4) Find a number such that seven less than twice the number is 43.
Translated: 2x - 7 = 43
x = 5) The length of a rectangle is four times its width. Its perimeter is 90 m. Find its dimensions. Use P = 2l + 2w.
Translated: 2(4w + w) = 90
width = m length = m 6) The total cost of a play station and a game is $291. The play station cost twice as much as the game. How much did the play station cost?
Translated: g + 2g = 291
a play station costs = $ 7) In one season, Ashleigh ran 18 races. This was four fewer races than twice the number races Crystal ran. How many races did Crystal run?
Translated: 2c -4 = 18
Crystal ran races. 8) The perimeter of a triangle is 51 cm. The lengths of its sides are consecutive odd whole numbers. Find the lengths of all three sides.
Translated: x + x+2 + x+4 = 51
short side = middle side = long side = 9) The length of a rectangle is 5 more than twice its width. Its perimeter is 88 feet. Find its dimensions. Use P = 2l + 2w.
Translation: 2(2w + 5 + w) = 88
Length: ft. Width: ft. 10) Justin hit four more home runs than twice the number of home runs Brandon hit. Together they hit 10 homeruns. How many home runs did Justin hit?
Justin's home runs + Brandon's home runs = 10 2b + 4 + b = 10
Brandon had home runs. Justin had home runs. |
