Answer:
2 miles per a hour
Step-by-step explanation:
m=miles
h=hours
1/2m=1/4h
if you times both sides by 4 you will get
2m=h
Given: <span>10g^2+33g=9-2g^2
Group the q^2 terms first, then the q terms, and finally the constants:
12g^2 + 33q - 9 = 0. Make sure you agree with this, or otherwise fix it.

I've graphed this simplified quadratic on my TI-83 calculator and see that -3 seems to be a root. Let's check it!
________________
-3 / 12 33 -9
-36 9
---------------------
12 -3 0 Since the remainder is zero, -3 is a root and (x+3) is a factor. The other factors are 3 and (4x -1)
Then 3(4g-1)(g+3) = 0, with the result that g = 1/4 and g = -3.
Please check these roots by subst. into the original equation.</span>
Cancel out the 2 with 8 in the denominator giveing you 4.
so, 3/4 * 1/7 = (3*1)/(7*4) = 3/28
