The perimeter of a rectangle is 24 meters. The width is nine meters less than twice the length. Which system of equations could be used to find the width, w, and the length, l, of the rectangle?
Hint: P=2l + 2w
w= 2l - 9
l + w = 24
w = 9- 2l
2l + 2w = 24
w = 2l - 9
2l + 2w = 24
w = 9l - 2
l + w = 24

A group of 19 people (adults and children) went to a concert for 5 hours. Each adult paid $9 and each child paid $4. Altogether the group paid $111. Find the system of equations that could be used to find the number of adults, a, and the number of children, c.
a + c = 111
9a + 4c = 19
a + c = 19
9a + 4c = 111
5a + 5c = 19
9a + 4c = 111
a + c = 19
5(9a + 4c) = 111

Mr. Leblanc saves nickels and dimes. If he has 28 coins worth $2.60, which system of equations could be used to find n, the number of nickels, and d, the number of dimes that Mr. Leblanc has?
n + d = 28
5n + 10d = 260
n + d = 2.60
.05n + .10d = 28
n + d = 28
.10n + .05d = 2.60
n + d = 28
.05n + .10d = 2.60
