6 miles as 31678 feet is 5 miles
The graph graphed is y=1/2x
so
y=1/2x and y=-x+6
y=y so
1/2x=-x+6
times 2 both sides
x=-2x+12
add 2x both sides
3x=12
x=4
sub back
y=1/2x
y=1/2(4)
y=2
(4,2) is the solution
Answer:
$819
Step-by-step explanation:
First we find the area of the wall so we multiply 13ft x 9ft.
13ft x 9ft = 117ft
We know each square foot is equal to $7. So now we multiply 117 x 7 to get the total cost.
117 x 7 = $819
Answer:
24 inches
Step-by-step explanation:
After folding the piece of paper, the result will be 1/4 the size of the original square. If you multiply the are of the triangle by 4, you will find that the area of the original square is 36 square inches. The square root of 36 is 6, which shows us that the length of each side of the square is 6. To get the perimeter, multiply 6 by 4 to get 24 inches.
