Answer:

32.4

Step-by-step explanation:

So if we divide 54 by 5 we get 10.8   ( her height

then we multiply 2 by her height which is   10.8 and that will give us 21.6 .

the last step is subtracting, So we get Sharon's height which is 54 and subtract that by 21.6 and that will gives us 32.4! :D

Solve the inequality 6t>t+6. Enter your answer as an inequality with just t on the left side. For example, if the inequality
ahrayia [7]

Answer:  t > 6/5

In decimal form, this would be t > 1.2

==============================================

Work Shown:

6t > t+6

6t-t > t+6-t ...... subtracting t from both sides

5t > 6

5t/5 > 6/5 .... dividing both sides by 5

t > 6/5

t > 1.2

Determine if the function f(x)=x+4 is increasing or decreasing on the interval of 2≤x≤5. Justify your answer.
Rudik [331]

Step-by-step explanation:

Given

The function is f(x)=x+4

for x_2>x_1, we will check the values of f(x_1) and f(x_2)

Take 3 and 4

f(4)=4+4\\f(4)=8

Similarly,

f(3)=3+4\\f(3)=7

Thus, f(4)>f(3)

Also, f'(x) is 1 i.e. a constant value. So, the function is increasing linearly for the given interval.

Using numbers 12,4,5,17,12 make 24. <br> Helllpppp
romanna [79]

Answer: To get 24

Step-by-step explanation

What you would need to do is first multiply 12 x 5 would come out as 60.

Then from 60 you subtract 17 and 12 to get 5. Divide by the 5 that you just got from 17 and 12 and to get 20. Using the 4 add it to the 20 to get 24.

Two trains leave the station at the same time, one heading west and the other east. The westbound train travels at 80 miles per
VashaNatasha [74]

Answer:

2.8 hours

Step-by-step explanation:

Distance = rate * time

If the west-bound train travels at a rate of 80 mph for t hours, then the distance it travels is 80t.  

If the east-bound train travels at a rate of 90 mph for t hours, then the distance it travels is 90t.

The distance between the trains after t hours is 476; therefore, the distance of the west-bound train plus the distance of the east-bound train equals the total distance between them, 476:

80t + 90t = 476 and

170t = 476 so

t = 2.8 hours
