Step-by-step explanation:
The opposites are -3, -7.5, and 2 2/3
2998 feet of glass was needed to cover the pyramid. You add 646 plus 350 and multiply by 3, which is the side length of the pyramid. (Pyramids or triangles have 3 sides.)
To find the x-intercept, set y=0 and solve for x.
To find the y-intercept, set x=0 and solve for y.
7x+6y=21
x-int: y=0
7x+6(0)=21
7x=21
x=3
y-int: x=0
7(0)+6y=21
6y=21
y=21/6 or 7/2
A. 168 feet
b. 1 yard = 3 feet
168*3=504 so, 168 feet =504 yards
c. 504 yards*$15=7560
d. $7560
