Answer:

\[B=\frac{C-Ax}{y}\]

Step-by-step explanation:

Given equation is:

\[Ax+By=C\]

Rearranging the terms by moving Ax to the right hand side,we get:

\[By=C-Ax\]

In order to find B , we need to divide both sides of the equation by y:

\[\frac{By}{y}=\frac{C-Ax}{y}\]

Simplifying:

\[B=\frac{C-Ax}{y}\]

So among the given options,option 1 is the correct one,namey,

\[B=\frac{C-Ax}{y}\]

Answer:

B = (C-Ax)/y

Step-by-step explanation:

Solve for B.

Ax+By=C

making B the subject of formula '

Ax+By=C

subtract Ax from both sides

By = C-Ax

By = C-Ax

divide both sides by y

B = (C-Ax)/y

What is a whole number
Vlada [557]

Answer:

Whole numbers are positive numbers (this includes 0) that do not have decimals or fractions to them.

Example:

1, 2, 3, 4, 5,etc are all whole numbers, because they are positive and do not have decimals or fractions

1.25 would not be a whole number, because although it is positive, it has a decimal.

When the positive integer n is divided by 7, the remainder is 2. What is the remainder when 5n is divided by 7?
ser-zykov [4K]

Therefore the reminder is 3 when 5n is divided by 7.

Step-by-step explanation:

we know that

Dividend = quotient × Divisor +Reminder

⇔ n = Q(n) × 7 + 2          [ let Q(n)  is quotient]

multiplying by 5 both sides

5n = 5 Q(n) ×7 + 2×5

⇔5n = 5 Q(n) ×7 +10

⇔5n=  5 Q(n) ×7 +7 +3

⇔ 5n = (5Q(n) +1) × 7 +3

Therefore the reminder is 3 when 5n is divided by 7.

Alex and Freddy collect stamps. The number of stamps in Alex’s collection to the number of stamps in Freddy’s collection is in t
vazorg [7]

Remark

The trick here is to realize that you have to find the number both have in order to find the difference. That means you take (effectively) 3/8 and 5/8 to find out how much each of them has. The 8 stands for the 136

Step One

Find the number of stamps Alex has. Remember his ratio is the smaller so he will have 3/8

Alex = 3/8 * 136

Alex = 408/8 = 51

Step 2

Find the number that Freddy has.

The total is 136

<u>Formula</u>

Freddy = Total - Alex

Freddy = 136 - 51

Freddy = 85

<u>Check</u>

Let us see if 5/8 * 136 = 85

5*136/8 = 680 / 8 = 85 So your answers are correct.

Difference

Difference = 85 - 51 = 34 which is how many more stamps Freddy has than Alex.
