Answer: 50 miles per hour
Step-by-step explanation:
The average speed of the car will be gotten by using the formula:
= Distance/Time
where,
Distance = 65 miles
Time = 14:48 - 13:30 = 1:18 hours = 1 hour 18 minutes = 1 18/60 = 1.3 hours
Speed = Distance / Time
= 65 miles / 1.3 hours
= 50 miles per hour
If you simplify what's in the bracket, you get 3n
=(3n)+4=32/2
=3n+4= 32/2(here we can either crossmultiply or equate)
3n+4-4=32/2-4(subtract 4 from both sides)
3n=32/2-4
3n=24/2
3n=12
3n=12(divide both sides by the coefficient of the unknown)
3n/3=12/3
n=4
Expression: x × y = x/2 × 2y
Answer:Your friend
Step-by-step explanation:
Well first I did was I found out that both 3 and 2 go into 12. 2 goes into 12 6 times. 9 * 6 is 54. 3 goes into 12 4 times. 11 * 4 is 44. 54 is greater than 44 therefore the answer would be your friend.
