Answer:
3=2x
Step-by-step explanation:
Distance is speed or velocity multiplied by time: d = v * t
We know the speed of the car and the time it travelled, so input the two into the equation above and solve for the distance travelled.
d = v * t
d = 64 m/h * (5 hours and 15 minutes) = 64 m/h * (5.25 hours)
d = (64 * 5.25) miles
d = 336 miles
ANSWER TO QUESTION 1

We multiply through by the Least Common Multiple which is 2.


We expand brackets to obtain,

Grouping like terms, have


Whenever you solve an equation and you get the above result, you don't have to get confuse.
It simply means the question does not have a UNIQUE solution.
That any real number will number will satisfy the above equation.
Hence,

ANSWER TO QUESTION 2

We factor x to obtain;

We divide both sides by (a+b)
Time = t = ?
Distance 1 = d1 = 224 miles
Distance 2 = d2 = 175 miles
speed1 = v1 = d1/t
speed2 = v2 = d2/t
Also, speed 1 = 14 + v2 (Given in the data)
OR speed 1 = 14 + d2/t
speed 1 = 14 + 175/t
224/t = 14 + 175/t
multiplying both sides (each term) by "t" we get
224 = 14t +175
OR 14t = 49
t = 3.5 hours
now, speed of 1st car = 224 miles / 3.5 hours
= 64 miles / hour
and speed of 2nd car = 175 miles / 3.5 hours
= 50 miles/ hour
Step-by-step explanation:
If we count for both numbers up to 36, we start seeing a pattern...
Candy: 6 12 18 24 30 36
Danny: 4 8 12 16 20 24 28 32 36
Every other number in Candy's counting is also counted by Danny. So here's what we'll do:
600/6 = 100
This is how many numbers Candy counted overall.
100/2 = 50
This is how many numbers Danny counted that were also numbers Candy counted.
Answer:
50 of the numbers that candy counted were also counted by Danny.
