What is division?

Division is the process by which value of single unit can be calculated from the value of multiple unit.

The number to be divided is known as dividend, the number by which the dividend is divided is the divisor, the result obtained is the quotient and the remaining part is the remainder.

There is a well known formula for division

Divisor x Quotient + Remainder = Dividend.

2b+8-5b+3= -13 -8b-5

Answers

In this question, you're solving for b.

Solve for b:

2b + 8 -5b + 3 = -13 - 8b - 5

Combine like terms:

-3b + 8 + 3 = -13 - 8b - 5

-3b + 11 = -13 - 8b - 5

-3b + 11 = -8b -18

Add 8b to both sides

5b + 11 = -18

Subtract 11 from both sides

5b = -29

Divide both sides by 5

b = -29/5

Answer:

Step-by-step explanation:

2b + 8 - 5b + 3 = -13 - 8b - 5....combine like terms

-3b + 11 = -18 - 8b ...add 8b to both sides

8b - 3b + 11 = -18...subtract 11 from both sides

8b - 3b = -18 - 11 ....combine like terms

5b = - 29...divide both sides by 5

b = -29/5 or - 5 4/5

There are 16 girls and 20 boys in the school band.
what is the ratio of girls to boys ?

Answers

To get the ratio we have to put into numerator number of girls and into denominator number of boys. Then simplify it
(16)/(20)= (16:4)/(20:4)= (4)/(5)
It also can be denoted as 4:5
the ratio of girls to boys is 4 to 5 in simplest terms. U need to divide both the 16 and 20 by 4, and u get 4 and 5. Since 4 represents girls, it comes first and the ratio is 4 to 5 or 4:5
