Each of them need to work 105 minutes more in order to have packed the same number of boxes.
<u><em>Explanation</em></u>
Suppose, they need to work for
minutes more in order to have packed the same number of boxes.
Selma packs one box in 5 minutes and Trudy packs one box in 7 minutes.
So, the number of boxes packed by Selma in that
minutes
and the number of boxes packed by Trudy in
minutes ![=\frac{x}{7}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bx%7D%7B7%7D)
Given that, Selma and Trudy have already packed 12 and 18 boxes.
Now if <u>each of them packed the same number of boxes</u>, then the equation will be......
![12+\frac{x}{5}=18+\frac{x}{7}\\ \\ \frac{x}{5}-\frac{x}{7}= 18-12\\ \\ \frac{7x-5x}{35}=6\\ \\ \frac{2x}{35}=6\\ \\ 2x= 210\\ \\ x= \frac{210}{2}=105](https://tex.z-dn.net/?f=12%2B%5Cfrac%7Bx%7D%7B5%7D%3D18%2B%5Cfrac%7Bx%7D%7B7%7D%5C%5C%20%5C%5C%20%5Cfrac%7Bx%7D%7B5%7D-%5Cfrac%7Bx%7D%7B7%7D%3D%2018-12%5C%5C%20%5C%5C%20%5Cfrac%7B7x-5x%7D%7B35%7D%3D6%5C%5C%20%5C%5C%20%5Cfrac%7B2x%7D%7B35%7D%3D6%5C%5C%20%5C%5C%202x%3D%20210%5C%5C%20%5C%5C%20x%3D%20%5Cfrac%7B210%7D%7B2%7D%3D105)
So, each of them need to work 105 minutes more in order to have packed the same number of boxes.
Answer:
60 mph
Step-by-step explanation:
Ms. Gayle drives 10 miles in just 10 minutes. To find out how fast she was going we need to turn the minutes into hours. There are 60 minutes in an hour, so we multiply the miles and minutes by 60.
Ms. Gayle drives 60 miles in an hour.
This means she is traveling at 60 mph.
I hope that this helps! :)
It's D, it's the only one where it has a -6 at the end other than A, but if you look at the A when distributed there isn't a 23x<span />
Answer:
m∠BCD = 120°
Step-by-step explanation:
Since the interior angles of a quadrilateral add up to 360°, then we get:
2x+x+2x+x=360°
6x=360°
<em>Divide both sides by 6</em>
x=60°
Since ∠BCD's value is 2x and x is equal to 60°, then ∠BCD is 120°.
