68.181 mph
300 feet/3 seconds = 100ft/sec
100ft x 60 sec. =6000ft/min
6,000 x 60= 360,000ft/hour
then convert to miles
It's 4. The factors of 12 are: 1,2,3,4,6,12. The factors of 20 are: 1,2,4,5,10,20.
Answer:
3
Step-by-step explanation:
I'm going to assume you mean:
13 * (3/4) + x = 7 * (1/4)
Let's go ahead and simplify the right side.
7 * (1/4) = 1.75
So now we have:
13 * (3/4) + x = 1.75
Now let's take care of the right side. Multiplication before addition.
13 * (3/4) = 9.75
9.75 + x = 1.75
To isolate x, we subtract 9.75 from both sides.
9.75 - 9.75 + x = 1.75 - 9.75
x = -8
Hopefully I spaced this well. \('-')/
It has 5 roots. You can determine this by the degree of the polynomial
