Answer:
The amount of yarn changes at 0.5 yards per hour.
Step-by-step explanation:
Since Kendra knits hats, and she starts with 3 3/4 yards of yarn, but after knitting for 5 1/4 hours, there is 1 1/8 yards of yarn left, to determine at what rate does the amount of yarn change the following calculation must be performed:
3/4 = 0.75
1/4 = 0.25
1/8 = 0.125
3.75 - 1.125 = 2.625
2.625 / 5.25 = 0.5
Thus, the amount of yarn changes at 0.5 yards per hour.
Answer:
<u>-24x² + 7x + 6</u>
Step-by-step explanation:
- (2 - 3x)(3 + 8x)
- 6 - 9x + 16x - 24x²
- <u>-24x² + 7x + 6</u>
Answer:
6 students have a cellphone and data to search for the author’s name.
That is less than 1/3 of the entire class.
Step-by-step explanation:
30 total students. Half is 15. 40% of 15 is 6. One third of 30 is 10. Which is more than 6.
The answer would be option A "Statement: 60 = 3x + 15; Reason: substitution." Remember that substitution means replacing something with something else. In this case you would be replacing variables separating the term and the variable in two different equations to get your answer.
![3x = 3 + \frac{3}{2}](https://tex.z-dn.net/?f=3x%20%3D%203%20%2B%20%5Cfrac%7B3%7D%7B2%7D)
![3x = x + \frac{x}{2}](https://tex.z-dn.net/?f=3x%20%3D%20x%20%2B%20%5Cfrac%7Bx%7D%7B2%7D)
Therefore your answer is indeed option A.
Hope this helps.
