Buses need to be ordered to transport the 426 students that signed up for a service project. If each bus holds a maximum of 33 students, what is the minimum number of buses needed?

Answers

Answer:

The answer is

Explanation:

First you would divide 426 by 33. And you would get 12.9090 etc. So you would round it up to 13.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

426 ÷ 33 = 13

The minimum number of buses needed to take all the students is 13 buses.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of students = 426

Number of students a bus can hold = 33

The number of buses needed to take 426 students.

= 426 / 33

= 12.9

= 13

Thus,

The minimum number of buses needed to take all the students is 13 buses.

find the perimeter of a rectangle with a length of 4x + 2 and a width of 2x

16x + 8
10x + 4
12x + 4
8x + 2

Answers

Answer:

12x+4

Step-by-step explanation:

To find the perimeter of any shape you just have to take the sum of all the sides.

In this case you would write:

 4x+2 (side 1) +2x (side 2) +4x+2 (side 3) +2x (side 4)

Now you just have to simplify the expression which would give you:

12x+4 (after collecting like terms)

So the final answer will be 12x+4

4x+2+2x=6x+2 which is the same as 12x+4
