When Tom found the difference −17 − (−12), he got −29. Complete the statement that explains what Tom might have done wrong.
ad-work [718]

Answer:

- 5

Step-by-step explanation:

Note that - (- 12) = + 12

Thus

- 17 - (- 12) = - 17 + 12 = - 5

It looks like Tom subtracted 12 from - 17, that is - 17 - 12 = - 29

Train A departs from Point A with a velocity of 100 km/h, Train B departs from Point B with a velocity of 200 km/h, and the dist
Bad White [126]

It would take 4 hours for both trains to meet.

Speed is the ratio of distance travelled to time taken. It is given by:

Speed = distance / time

Let t represent the time at which both trains meet, and d represent the distance covered by train A, hence:

For train A:

100 = d / t

t = d/100

For train B:

200 = (1200 - d) / t

t = (1200 - d) / 200

d/100 = (1200 - d)/200

2d = 1200 - d

3d = 1200

d = 400 km

t = 400 / 100 = 4 hours

It would take 4 hours for both trains to meet.

Anne-marienhas saved 9 dollars for a new coat that is 1/6 as much money as she needs how much does the coat cost
Tatiana [17]

Answer:

Cost of the coat = $54

Step-by-step explanation:

Given:

She saved = $ 9

To Find:

Cost of the coat = ?

Solution:

Let the price of coat be x

She saved $9

and according to given condition it is 1/6 of the total money she needs for buying coat

by this we have

\frac{1}{6}*x = 9

Multiplying both sides by 6

\frac{1}{6}*x*6 = 9*6

it becomes

x = 9*6

x = $54

As x is the amount she needs

so

Cost of the coat = $54
