Answer: There are 45 boys
Step-by-step explanation:
3:4
60÷4=15
15×3
=45
For this case we must simplify the following expression:
We solve the operation of the second parenthesis, taking into account that different signs are subtracted and the sign of the major is placed:
We multiply:
We eliminate the parentheses:
We add similar terms, taking into account that equal signs are added and the same sign is placed:
Answer:
The simplified expression is:
The maximum possible number of people on the train is 183.
Given that a train has 11 train cars, and at least 11 passengers are in each train car, and no 3 neighboring train cars have more than 50 passengers altogether, to determine what is the maximum possible number of people on the train, the following calculation must be done:
- 50/3 = 16.66
- 16 + 17 + 17 = 50
- 16 + 17 + 17 + 16 + 17 + 17 + 16 + 17 + 17 + 16 + 17 = X
- 16 x 4 + 17 x 7 = X
- 64 + 119 = X
- 183 = X
Therefore, the maximum possible number of people on the train is 183.
