You use 33 cans of soup to serve 55 people. If you want to serve 2020 people, what should you do?
sveticcg [70]
First off, we need to find how much would a people need,by dividing the amount needed.

The equation of how much a people would need:

55÷33
=1.67 or 55/33 (it would be best to keep it in fraction to get a more precise answer)

To find out how much 2020 people need ,we would mutiply the answer above by 2020:

55/33×2020
≈3366.7
≈3367

Thus,you would have to prepare 3367 can of soup.

hope it helps!

posledela

Answer:

x+y= 59,  x-y= -13

Step-by-step explanation:

We know that x is the smaller number and y is the bigger number. We also know that the difference is 13, meaning x-y= -13. Since the sum of the two numbers is 59, x+y= 59

Which of the following equations is of a parabola with a vertex at (3, 0)?
bixtya [17]

Answer:

D. y = (x - 3)²

Step-by-step explanation:

The parabola formula in vertex form is:

y = a(x - h)² + k

where the vertex is located at (h, k). Replacing with vertex (3, 0) we get:

y = a(x - 3)² + 0

y = a(x - 3)²

In all possible options the leading coefficient <em>a</em> is equal to one. Therefore:

y = (x - 3)²

Y=x+5<br> 4x+y=20<br> Solving system by substitution
sineoko [7]
Y = x + 5....so we sub in x + 5 for y in the other equation

4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3

y = x + 5
y = 3 + 5
y = 8

solution is (3,8)
