Answer:

look below

Step-by-step explanation:

i dont know what that +... thing is

but when youre adding the negatives youre really just adding that number so this is just

48+45+42+81+84

45+42 is 87

now we have

48 + 87 + 81 + 84

87 + 81 is 168

48 + 84 is 132

now we have

168 + 132 and that is exactly 300

again dont know what the ... is so cant help you there

There are 1200 students at a school and 390 of them are boys if each classroom holds 30 students how many classrooms are needed

vodomira [7]

Answer:

40 classrooms

Step-by-step explanation:

Divide 1200 by 30.

1200÷30=40

If 390 students are boys just subtract 390 from 1200.

1200-390= 810

There must be 810 girls if there are 390 boys
