The complete question in the attached figure
we know that
[<span>amount of fabric]=8*[area of lateral triangle side]
area of lateral triangle side=(1/2)*4*5----> 10 ft</span>²
so
[amount of fabric]=8*[10]----> 80 ft²
the answer is80 ft²

Please check explanations
Step-by-step explanation:
Slopes are generally the ratio of rise(vertical difference) to fall (horizontal difference) for set of points lying on a straight line
Positive slopes show a positive relationship between the two things we are considering while a negative one shows otherwise
They are the same in the sense that they actually represent a constant change between the coordinates of the points in the relationship we are considering.
They are different in the sense that while one represents a positive change, whereby both axes move in the same direction ( rise at same rate, fall at same rate) , the second represent a relationship in which they move in opposite directions. While one falls, the other rises and while the other rises, the second one falls which indicates an opposing movement type between the two
$63. 1.5 hrs
$x. 4 hrs
63/x=1.5/4
x=63•4/1.5
x=252/1.5
x=168$
Answer:
Here
Step-by-step explanation:
We move all terms to the left:
7+9x-(6x-2)=0
We get rid of parentheses
9x-6x+2+7=0
We add all the numbers together, and all the variables
3x+9=0
We move all terms containing x to the left, all other terms to the right
3x=-9
x=-9/3
x=-3
3x + 5y = 1 . . . . . . . . (1)
7x + 4y = -13 . . . . . . .(2)
(1) x 7: 21x + 35y = 7 . . (3)
(2) x 3: 21x + 12y = -39 .(4)
(3) - (4) = 23y = 46
y = 46/23 = 2
