A printer takes 30 minutes to print a banner and a poster. I will take 50 minutes to print a banner and three posters. How long
qwelly [4]

Answer:

It takes the printer 20 minutes to print a banner

Step-by-step explanation:

Notice that there are two unknowns in this problem: the time to print a poster and the time to print a banner. Let's assign the letter "b" to the time it takes to print a banner, and "p' the time it takes to print a poster.

So we can write the following two equations involving the total amount of time that takes to print in the two cases:

b+p=30\\b+3p=50

We can solve for the unknown "p" by subtracting term by term in the equation set above:

b+3p=50\\b+p=30\\\\b-b+3p-p=50-30\\2p=20\\p=10

So it takes 10 minutes to print each poster, we can find the time it takes to print the banner by using the value we just found in one of the equations:

b+p=30\\b+10=30\\b=20

So, it takes 20 minutes to print a banner.

Elenna [48]

Answer

In decimal form it is 1.25 and in fraction form it 1/4

Step-by-step explanation:

There might be and there are other ways but the way I did it is I  converted the fractions to decimals. 1 3/4= 1.75, 1 1/2= 1.5, and 4 1/2 equals 4.5. So I added the time he practiced on Monday and Tuesday and subtracted it from the final hour of the whole entire week and the answer is 1.25 or 1/4
