Answer: 190

Step-by-step explanation: Afterwards whenever you add the totals you should add because that would be the last thing to do in situations like this. Also, you have to add 32 + 8 + 30 + 120 which equals to 190. Actual Answer Unlike The Other One

Ali hops on his 3 wheeler and heads off at 12 mph. Two hours later, Fatimah chases after him on a moped at 18 mph. How far will
mash [69]

Answer: 72 miles.

Step-by-step explanation:

We know the relationship:

Distance = speed*time.

Then we can write the equation for distance as a function of time for Ali as:

A(t) = 12mph*t

where t is time in hours.

Fatimah's equation will be:

F(t) = 18mph*(t - 2h)

where the -2h appears because she starts two hours after Ali.

Fatimah will overtake Ali when F(t) = A(t) (their positions are the same)

Then we need to solve:

12mph*t = 18mph*(t - 2h)

12mph*t = 18mph*t - 18mph*2h

12mph*t = 18mph*t - 36 mi

36 mi = (18mph - 12mph)*t

36mi = 6mph*t

36mi/6mph = t

6h = t

So Ali travels for 6 hours before he gets overtaken, then the total distance that Ali travels is:

A(6h) = 12mph*6h = 72 mi

Point C is on line segment \overline{BD} BD . Given BC=x+4,BC=x+4, CD=5x,CD=5x, and BD=5x+7,BD=5x+7, determine the numerical len
aleksandrvk [35]

Answer:

CD = 15

Step-by-step explanation:

Given

BC = x + 4

CD = 5x

BD = 5x + 7

Required

Determine CD

Since Point C is on segment BD, then we have

BD = BC + CD

Substitute x + 4 for BC; 5x for CD and 5x + 7 for BD

5x + 7 = x + 4 + 5x

Collect Like Terms

5x - 5x - x = 4 - 7

- x = -3

Multiply both sides by -1

x = 3

Substitute 3 for x in CD = 5x

CD = 5(3)

CD = 15

<em>Hence, the length of CD is 15 units</em>
