You will need 3 cans of paint to cover the two walls

<h3>How many cans of paint will you need?</h3>

We know that 1 can will cover 200 square feet of wall.

And here we have 2 walls, let's find the total area of these walls.

wall 1 is 20ft by 8ft, then its area is:

A = 20ft*8ft = 160ft^2

wall 2 is 40t by 8 ft, then its area is:

A'  = 40ft*8ft = 320ft^2

The total area is:

160ft^2 +  320ft^2 = 480ft^2

The number of cans of paint needed is given by the quotient between the total area and the area that each can cover.

N = 480ft^2/200ft^2 = 2.4

But we can't have a 0.4 of a can, so we should round to the next whole number, which is 3.

Desmond ordered his favourite pizza with 1 2 12 slices. Sadly, he could finish only 7 5 % 75% of the whole pizza. How many pizza
Gala2k [10]

Answer:

3 pizza slices.

Step-by-step explanation:

We have been given that Desmond ordered his favorite pizza with 12 slices. Sadly, he could finish only 75% of the whole pizza.

As Desmond ate 75% of 12 slices, so left number of slices will be equal to 25% of 12 slices.

\text{Number of pizza slices left}=\frac{25}{100}\times 12

\text{Number of pizza slices left}=\frac{1}{4}\times 12

\text{Number of pizza slices left}=3

Therefore, 3 pizza slices were left.

Examine this system of equations. Which number can be multiplied by each equation so that when the two equations are
andreyandreev [35.5K]

Answer:

15 times the first equation and -12 times the second equation

Step-by-step explanation:

we have

\frac{3}{4}x+\frac{2}{3}y=6 ------> first equation

\frac{5}{8}x+\frac{5}{6}y=12 ------> second equation

Multiply the first equation by 15 both sides

(15)\frac{3}{4}x+(15)\frac{2}{3}y=6(15)

\frac{45}{4}x+10y=90 -----> new first equation

Multiply the second equation by -12 both sides

(-12)\frac{5}{8}x+(-12)\frac{5}{6}y=12(-12)

-\frac{60}{8}x-10y=-144 -----> new second equation

Adds the two new equations

\frac{45}{4}x+10y=90\\-\frac{60}{8}x-10y=-144\\-----------\\\frac{45}{4}x-\frac{60}{8}x=90-144

The y-term was eliminated
