Answer:
C
Step-by-step explanation:
To get the approximate number of pages in the chapters, what we need to do is to substitute for the value of x in the line of best fit equation.
Thus, we have;
y = 15.261(8) + 8.83 = 122.088 + 8.83 = 130.918
This is approximately equal to 131
You have to get y by itself. Divide by 7 on both sides to get 1.43x-11=y. Hope this helps! ;)
Answer: 33.041666
Step-by-step explanation:
Given: The translated equation : 
To find the value of x if y = 87.5, we need to substitute the value of y in the given translated equation, we will get

Subtract 87.5 from both the sides , we get

Now, divide 300 on both the sides, we get

The number of hours Jeremiah ironed = 10 hours
The number of hours Tristan ironed = 7 hours
<u>Step-by-step explanation</u>:
- Jeremiah can iron = 35 shirts per hour
- Tristan can iron = 20 shirts per hour
- Total work done by both = 490 shirts
Let 'x' be the number of hours Jeremiah ironed.
Let 'y' be the number of hours Tristan ironed.
x+y = 17 ------(1)
35x + 20y = 490 -------(2)
Multiply (1) by 20 and subtract (2) from (1),
20x + 20y = 340
-(<u>35x + 20y = 490</u>)
<u>-15x = -150 </u>
x = 150/15
x = 10
Substitute x=10 in (1)
10+y = 17
y = 7
No I don’t think it’s possible
