Hi
The correct option is 4r + 1 = 3r + 5
-------------------------------------------------------
Because you need to solve q = 4r + 1 for q . After that, you'll have to substitute 4r + 1 for q in q = 3r + 5
Good luck!

I think the interquartile range is 13. Hope it help!
Answer:
The maximum temperature will be of 85 degrees, on July 15.
Step-by-step explanation:
Sine function:
The sine function oscilates between -1 and 1, and it's maximum value is:
y=60+25sin(pi/6)t
The maximum value will occur when 
, and it will be of 60 + 25 = 85 degrees.
When will it occur?
First we find the value of t for which the value inside the function sine is 
. So
That is the number of months after April 15, which is 3 months. So July 15.
Combine like terms on the left side of the equation. Add 4 and 2 and subtract x and 2x. After combining like terms you should get: 6 - x = 5.
Subtract 6 from both sides to isolate x. Now you have: -x = -1. Make x into a positive by dividing both sides by -1. You are correct - the answer is x = 1.
There is no choice on your list that must represent an odd integer.
If 'z' is an even integer, then (z-1) and (z+1) must both be odd integers.
