Andrew is 50 years younger than Natasha. 6 years ago, Natasha's age was 3 times Andrew's age. How old is Andrew now?

jok3333 [9.3K]

Natasha's age is 81 years and Andrew's age is 31 years

Step-by-step explanation:

Step 1: From the given details, let the age of Natasha be x, then age of Andrew is x - 50.
Step 2: Form equations out of their details of ages 6 years ago.

⇒ x - 6 = 3(x - 50 - 6)

⇒ x - 6 = 3(x - 56)

⇒ x - 6 = 3x - 168

⇒ 2x = 162

⇒ x = 81

Step 3: Calculate Andrew's age

x - 50 = 81 - 50 = 31

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.
