Writing Systems Pt 2 For each situation, write two equations that fit the situation.

The perimeter of a rectangle is 76. The width is two feet longer than the length. 1.

Damien bought 46 pounds of apples and grapes for $ If apples are $1.76 a pound and grapes are $2.15 a pound, write two equations given the situation. 2.

The perimeter of a rectangular wooden deck is 90 feet. The deck’s length, l, is 5 feet less than 4 times its width, w. Which system of linear equations can be used to determine the dimensions, in feet, of the wooden deck? F 2l + 2w = 90 H 2l + 2w = 90 l = 5 – 4w l = 4 – 5w G 2l + 2w = 90 J 2l + 2w = 90 l = 5w – 4 l = 4w – 5 3.

The Frosty Ice-Cream Shop sells sundaes for $2 and banana splits for $3. On a hot summer day, the shop sold 8 more sundaes than banana splits and made $156. Which system of equations could be used to find the number of sundaes, s, and banana splits, b, that the shop sold that day? A 2s + 3b = 156 C 2s + 3b = 8 s = b + 8 s = b B 2b + 3s = 156 D 2s + 3b = 156 s + b = 8 b − s = 8 4.

Alexis has a jar of nickels and dimes that is worth $ There were a total of 412 coins in the jar. Write to equations to go along with the situation. 5.

Mark bought 5 snickers and 3 suckers for a total of $7.09. Chyian bought 8 snickers and 1 sucker for a total of $ Write two equations to go along with the situation. 6.

The perimeter of a rectangular volleyball court is 180 feet. The court’s width, w, is half its length, l. Which system of linear equations could be used to determine the dimensions, in feet, of the volleyball court? A l + w = 180 B 2l + 2w = 180 w = l w =.5l C l + w = 180 D 2l + 2w = 180 l = w l =.5w 7.

Juli has a jar full of quarters and pennies. There are a total of 670 coins in the jar and it adds up to $ Write two equations to go along with the situation. 8.

A school principal ordered 100 pizzas for a total of $1255. Cheese pizzas cost $11.50 each, and pepperoni pizzas cost $13.00 each. Which of the following systems of linear equations can be used to determine c, the number of cheese pizzas the principal ordered, and p, the number of pepperoni pizzas the principal ordered? A c + p = 100 C c + p = c p = c + 13p = 1255 B c − p = 100 D c − p = c p = c + 13p =
