Look at the denominators. The second fraction's denominator is 3 times the first fraction's denominator. Since the fractions are equal, it means you have to multiply the first fraction's numerator by 3 too. So, b=9. Good luck!
Well, you already know how much she stuff per hour, but you still need to find out how much per minute. And in one hour, there are 60 minutes.
So you divide the amount in an hour by 60 minutes, meaning you divide : 228 ÷ 60 = ?
And once divided, you get 3.8. So that would mean that she stuffs 3.8 envelopes per one minute, so that means nearly 4, but since you aren't asked to round, I'd say to just go for the average rate, which is 3.8
You can check your work by using a calculator or using another method to find the same answer to the same question. You could also ask a friend
Pleaze mark brainliest!!
I don’t really need to you can come to my
The difference between Tucker and Karly's take is that Tucker's solution is analytical while Karly's is graphical. But both are correct either way.
For Tucker's solution, let's say at x=-3 the value for y is 4, and at x=3, the value of y is still 4, then the average rate of change or slope is 0. Note that the slope of the curve is Δy/Δx. Since there is no change for Δy, the slope is zero.
For Karly's solution, even if the curve travels high or low but would have the same elevation of x=-3 and x=3, the average rate of change is still zero. It is actually just same with Tucker's but Karly just verbalizes her solution that was observed visually.
