Jonah studied for 3 hours longer than sierra he also studied for 3 times as many hours as william. these relationships are shown on the graph below. which statement is true if jonah studied for 6 hours

Sierra studied 3 hours

William studied 2 hours

Step-by-step explanation:

jonah studied 6 hours.

He also studied 3 hours longer than sierra meanining sierra studied 3 hours less than 6 hours.

So, 6 hours minus 3 hours is equals to 3 hours.

With that being said, Sierra has studied 3 hours.

Sierra = 3 hours

The question then states that Jonah studied 3 times as many hours as William.

Reminder: Jonah studied 6 hours in total.

This means that jonahs' hours (6 hours) is equals to 3 times williams hours (3x)

6 hours= 3x                        

x= williams hours

we divide both sides by 3 to see what x is equals to

in other words, we divide Jonahs' hours to see what williams hours are

With that being said, William studied for 2 hours

2 hours = x

Sierra studied for 1 hour longer than William

Step-by-step explanation:

Because Sierra studied for 3 hours and William studied for 2 hours. 3-2=1

x + 4/7

step-by-step explanation:

use cymath

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
