Step-by-step explanation:
To cover a rectangular region of her yard, Penny needs at least 217 square feet of sod. The length of the region is 15.5 feet. What are the possible widths of the region?
L=length=15.5 ft; W=width; A=area=>217 sq ft
L*W=>217 sq ft Divide each side by L
W=>217 sq ft/L
W=>217 sq ft/15.5 ft=>14 feet
ANSWER: To cover at least 217 sq ft. the width must be at least 14 feet.
Answer:
D (7, 0.5)
Step-by-step explanation:
The equations must be interpreted to be ...
A graph shows the solution to be (7, 0.5), matching selection D.
___
You can add the two equations together to get ...
(y) +(y) = (-1/2x +4) + (1/2x -3)
2y = 1 . . . . . simplify
y = 1/2 . . . . .divide by 2
It can be convenient to use the second equation to find x.
1/2 = 1/2x - 3
1 = x - 6 . . . . . . multiply by 2
7 = x . . . . . . . . . add 6
The solution is (x, y) = (7, 0.5). . . . . matches selection D.

Answer:
The number of adult tickets sold was 121
Step-by-step explanation:
The general equation is: <em>S</em> + <em>A</em> = <em>T</em> ;where <em>S</em> means student tickets, <em>A</em> means adult tickets and <em>T</em> means total tickets. We know that <em>S</em> is two times <em>A</em> and <em>T</em> is 363. So, <em>S</em> will be 2x and A will be x. Then, the new equation is 2x + x = 363.
<em>S</em> + <em>A</em> = <em>T</em>
2x + x = 363
3x = 363
x = 363 / 3
x = 121
Adult tickets: <em>A</em> = x = 121
Student tickets: <em>S</em> = 2x = 2 * 121 = 242
