73 feet per second
Steps-
Miles to cover- 50 miles = 50*5280 feet = 264,000 feet
Time it takes- 1 hour = 1*60*60 seconds = 3,600 seconds
So speed is- 264,000 feet per 3,600 seconds = 264,000 / 3,600 = 73.33 ft per second
Multiply the bracket by 1/2
1/2(2n +6)
cross out 2 and 2n and divide by 2.
cross out 6 and 2 and divide by 2
n+3
Answer is n+3
As you can see, every time x increases by 2, y decreases by 5.
So, we have
66.15/0.63=105
The answer is 105.
-160=22+8(3p-4)
Use distributive property
-160=22+24p-32
-160=24p-10
Add 10 for both side
-160+10=24p-10+10
-150=24p
Divided 24 for both side
-150/24=24p/24
p=-6.25
Check:
-160=22+8(3p+4)
-160=22+8[3(-6.25)-4]
-160=22+8(-18.75-4)
-160=22+8(-22.75)
-160=22-182
-160=-160. As a result, x=-6.25. Hope it help!
