This is written as:

21 - 2(10 - 3^2) + 4 and is an expression, not an equation.

The work inside ( ) must be done first: 21 - 2(10 - 3^2) + 4 => 21 - 2(10 - 9) + 4, and, continuing, this gives us 21 - 2 + 4. That sums up to 23 (answer).

A group of teachers and students will take a bus trip to a museum, and each teacher will lead a group of no more than 4 students
ValentinkaMS [17]

Answer:

A maximum of 43 students and 11 teachers can go to the trip.

Step-by-step explanation:

Since a group of teachers and students will take a bus trip to a museum, and each teacher will lead a group of no more than 4 students, and the bus can hold a maximum of 54 teachers and students, to determine the possible numbers of teachers and students who can go on the trip, the following calculation must be performed:

4 + 1 = 5

54/5 = X

10.8 = X

10 x 4 = 40

10 x 1 = 10

4 - 1 = 3

Therefore, a maximum of 43 students and 11 teachers can go to the trip.
