Answer:
If she walked 3.5 miles in 1.4 hours, then her pace was:
3.5 miles / 1.4 hours = 2.5 miles/hour
Step-by-step explanation:
To get her pace in miles per hour, you take the number of miles and divide by the number of hours.

Answer:
88 score.
Step-by-step explanation:
Given:
To get a B in math, Alexandria Pappas must<u> average 80</u> on five tests.
Scores on the first four tests were <em>82, 74, 82, and 74.</em>
Question asked:
What is the lowest score that she can get on the last test and still get a B?
Solution:
Let lowest score she can get on the last test = 
As we know:
By cross multiplication:-
Thus, she can get 88 score on the last test to get a B in math.
<span>x 2 3 4
f(x) 5.5 7 8.5 </span>
The first function is linear. When you subtract 5.5 from 7, you get 1.5 and when you subtract 7 from 8.5 you also get 1.5. That's how we know it's a linear function because there's clearly pattern. HOWEVER, if you had 5.5, 7, and 9 that would not be a linear function. Why? Because when you take away 7 from 9 you get 2. In order for it to be a linear function you have to get the same exact number when you subtract.
<span>x 0 3 6
f(x) 1 8 64</span>
The second function is exponential because when you divide you get the exact same number. 8/1 = 8 and 64/8 = 8. So this is exponential. But if you had 72 instead of 64 it would not be an exponential function because there has to be a pattern.
I hope this makes sense. Btw I had this question on my test too and this is correct.
(2x+4) +(3x-1) +(x+1)=34
6x+4=34
x=5
AB=14, BC=14, AC=6
