One number is less than a second number. Twice the second number is 42 more than 4 times the first?

Any pair of numbers (x, 21 + 2x).

Step-by-step explanation:

I am going to solve this question building a system of equations. We have that:

The first number is x

The second number is y.

Twice the second number is 42 more than 4 times the first

This means that:

2y = 42 + 4x

Dividing by 2

y = 21 + 2x

So the solution to this question is:

Any pair of numbers (x, 21 + 2x).

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
