This is a trick question. First just understand that any number over itself is 1 so

is just

so it is just

cups of cheese is needed to make 10 pizzas.
<u><em>Explanation</em></u>
For making one pizza, amount of cheese needed =
cups =
cups.
Now for finding the total amount of cheese needed to make 10 pizzas, we need to <em>multiply
cups by 10. </em>
So, 
Thus,
cups of cheese is needed to make 10 pizzas.
Answer:
The equation of the straight line is 4x +y = 1
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given points are (-1,5) and ( 2,-7)
Slope of the line

slope of the line m = -4
<u><em>Step(ii):-</em></u>
The equation of the straight line passing through the point (-1,5) and having slope 'm' = -4

y - 5 = -4 ( x-(-1))
y -5 = -4 x -4
4 x + y -5 +4=0
4x +y -1 =0
<u><em>Final answer:-</em></u>
The equation of the straight line is 4x +y = 1
<u><em> </em></u>
