Answer:

x = 8

y = 11

Step-by-step explanation:

Total small box weight  = 50x    [x being the number of small boxes]

Total large box weight = 80y     [y being the number of large boxes]      

Total boxes = x+y = 19

Total weight = 1280

<em>Determine x and y.</em>

<u>You know 2 equations. One for weight and another for number of boxes each.</u>

  • 1280 = 50x +80y
  • x+y = 19

<u>Rewrite second equation:</u>

x+y=19

y=19-x

<u>You have to plug in one into another.</u>

1280 = 50x + 80(19-x)

<u>Solve for x</u>

1280 = 50x + 1520 - 80x

-240 = -30x

x = 8

<u>Solve for y by plugging in x into one of the equations:</u>

8+y = 19

y = 11

Plz help me solve this
Nady [450]

Answer:

c = 9.43 cm

Step-by-step explanation:

Here, we want to get the measure of the missing side

By the use of Pythagoras’ theorem, the square of the hypotenuse equals the sum of the squares of the two other sides

we have this as follows;

The side c represents the hypotenuse as it faces the hypotenuse

We have this as;

c^2 = 5^2 + 8^2

c^2 = 25 + 64

c^2 = 89

c = √89

c = 9.43 cm
