-13 (q + 4) = 7q + 16
I think to solve it you do this first:
-13q + -52 = 7q + 16
And then I think you do:
-6q + -36
And thats all I can remember sorry ):
Or
That -6q + -36 might be the answer I think (:
Hope I could help (:
Answer:
520 out of 800 students ride the bus
Step-by-step explanation:
Given


Required
Determine the number of students 
To do this, we simply multiply the proportion by the total number of students.
i.e.


Express the percentage as decimal

Answer:
The first one is proportional and the second one is not. Because for the first one you can see that if you divide the number of pens by the cost you'll get the same answer for every single one. But for the second one if you divide the number of minutes by words typed you get a different answer for each one. You can also see if it's proportional or not if you draw it on the graph and it's a straight line. If it is the relationship is proportional if it isn't it's not proportional. Hope that makes sense :)
Answer:
4
Step-by-step explanation:
because 32 divided by 8 = 4
C) $694.25
Why?
Because you want to times the interest by 2 (1 is for one year but u want to find the amount after two years) then you multiply the amount given to each bank separately so:
400*0.07 (7% which is 7/100) = 28
250*0.065 (6.5% which is 65/1000) = 16.25
Then u add the interests together:
28+16.25 = 44.25
Finally you add that to the amount you started with:
$650+$44.25= $694.25
