The number of pages read varies directly as the number of minutes. if you can read 20 pages and 45 minutes, how many pages can you read in 18 minutes?

The number of pages that you can read in 18 minutes is equal to 8 pages.

Given the following data:

To determine how many pages you can read in 18 minutes, we would apply direct proportion:

By using direct proportion:

20 pages = 45 minutes

X pages = 18 minutes

Cross-multiplying, we have:

X = 8 pages

8 pages

Step-by-step explanation:

Write and solve an equation of ratios:

20 pages           x

=

45 min          18 min

Cross multiplying, we get (18 min)(20 pages) = (45 min)x.

Then x = (18)(20)/(45) pages = 360/45 pages = 8 pages

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

is only a line? i think so
