Shelly needs to read a novel for English class. She can read at a rate of 9 pages per hour. After 3 hours, she is on page 52.
Which equation models the situation?
y−3=−9(x−52)
y−3=9(x−52)
y+52=9(x+3)
y−52=−9(x−3)
y−52=9(x−3)
I thincc B
the last one
star is right
Ok thanq
To find the equation that models the situation, we need to consider the information given in the problem.
First, we know that Shelly can read at a rate of 9 pages per hour. This means that she reads 9 pages in one hour.
Second, after 3 hours, Shelly is on page 52. This means that in 3 hours, she has read 52 pages.
We can use this information to create the equation. Let's break down the information:
Rate of reading: 9 pages per hour
Time spent reading: 3 hours
Total number of pages read: 52
To express the total number of pages read based on the time spent reading, we can use the equation:
Total number of pages read = Rate of reading × Time spent reading
Plugging in the values we have:
52 = 9 × 3
Simplifying the equation:
52 = 27
Since the equation doesn't hold true, this means that none of the given options is the correct equation that models the situation.
