Answer:
39.96 miles
Step-by-step explanation:
The first step is to find how long he drove in yards. yards. Now, we need to convert it into feet. A yard is exactly three feet, meaning that he drove feet. Finally, we need to find how many miles he drove. It is known that there are 5280 feet in a mile, so you just need to divide the number of feet he drove by the number of miles to find that he drove 210998.8/5280=39.96 miles. Hope this helps!
1. Solution: X= -2.5
Steps:
0= 2x +5
-2x=5
X= -5/4
2. Solution: x=3
Steps:
0=(x-3)2
(X-3)2 = 0
X-3=0
X=3
Answer: I think it’s 1/3
Step-by-step explanation:
(x^2+5x-36)/(x^2-16)
=(x^2+9x-4x-36)/(x^2-4^2)
=x(x+9)-4(x+9)/(x+4)(x-4)
=(x-4)(x+9)/(x+4)(x-4)
=x+9/x+4
Hope this helps.
