Use the five-step strategy for solving word problems to find the number or numbers described in the following exercise: when four times the number is added to 7 times the number, the result is 44. what is the number?

Let the unknown number be 'x'.

Since, four times the number is added to 7 times the number, the result is 44.

Four times the number = 4x

Seven times the number = 7x

The sum of these numbers is 44.

So, 4x + 7x = 44

11x = 44

x = 4

Hence, the number is 4.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
