Answer:

5.) y = 170t

6.) By finding the common rates (slope) (rise over run or y/x)

7a.) Car two isn't going at the constant speed

7b.) They relate by they would still carry the same factors 40mph(from car#2), and 80mph (from car #4) have a common factor of 40 and 35mph (from car #2) and 70mph (from car #4) would have a common factor of 35)

Step-by-step explanation:

(for #5) "t" would mean time as in for hours and the 170 is considered as "m" in the equation of (y=mt+b) and there isn't a starting point of when the bullet trained have already drove (which would have been the number for "b")

So your equation for this would have been y=170t

(For #6) in order for the table or the relationship to be proportional, there must be a constant slope, so the equation would be (when doing it algebraically)

\frac{x_{2} -x_{1}  }{y_{2} -y_{1} } or there is a constant adding (like for example in car 3, the y sections would add by 20 not multiply)

( Or when looking at the table)

for every pair, when you \frac{y}{x} for every pair, it should led you to the same number

so in car 2, everything had the constant speed of 35mph except when dividing \frac{y}{x} for 800/20, it gave us 40mph instead of 800

(For #7a) same thing for #6 but i was using the question from 7a to explain the explanation for #6

(For #7b) (I hope it was easy to understand on what I was talking about)

(Helper's note: I hope it was easy to understand, I tried my best to explain with words [as you can see not good at explaining in words but in numbers haha] )

Faith is tracking the number of burpees she does at a constant rate. Last
bija089 [108]
This is a unit rate question. We can solve this in chronological order of steps:

Step 1: Write out the beginning for the first unit rate.

Faith completed 60 burpees in 5 minutes last week.

Step 2: Since 60 burpees were completed in 5 minutes, we can divide 60 by 5 to find how many burpees were completed in 1 minute.

60 divided by 5 equals 12.
5 divided by 5 equals 1.

Our fraction for how many burpees Faith did in a minute last week is 12/1. This reduces to 12, meaning that Faith did 12 burpees last week.

Step 3: Find the unit rate for this week.

Faith completed 78 burpees in 6 minutes this week. Because of this, we can divide 78 by 6 to find how many burpees Faith completed this week.

78 divided by 6 equals 13.
6 divided by 6 equals 1.

Our final fraction for how many completed burpees Faith did this week is 13/1, which reduces to 13. Therefore, Faith completed 13 burpees per minute this week.

Your final answer: In terms of separate values, Faith completed 12 burpees per minute last week and 13 burpees per minute this week. If you need help, let me know and I will gladly assist you.
