A baker was going to arrange 432 desserts into rows of 28. The baker divides 432 by 28 and gets a quotient of 15 with remainder of 12. Explain what the quotient and remainder represent

Answers

The quotient of 15 represent the number of desserts in each row

The remainder represent the rest of the dessert does not meet the 29th line (only 12 from 15)

Further explanation

The division operation is one of the basic arithmetic operations

Common signs used are \boxed{:}} or \boxed{\slash}}

The division is written by placing the numerator above the denominator with a horizontal line between them or use a slash with the numerator's position and the denominator is parallel

The division is actually an iterative subtraction operation (as many as the number of divisors)

Division is the opposite of multiplying

The general form of division can be stated by:

\boxed{\bold{divident:divisor=quotient+remainder}}

example:

7: 3 = 2 + 1

  • 7 = dividend
  • 3 = divisor
  • 2 = quotient
  • 1 = remainder

The form of division can also be expressed in terms of fractions

In the number above, the form of fraction obtained is the form of mixed fractions

Mixed fractions consist of integers and ordinary fractions

mixed fractional form :

\displaystyle {2(1)/(3)

Mixed fractions can be expressed as ordinary fractions :

\displaysyle {=(7)/(3) }

Division operation statement:

"7 divided by 3 equals 2 remainder 1"

When dividing 432 desserts into rows of 28, the baker finds a quotient of 15 with a remainder of 12

Division operation statement:

"432 divided by 28 equals 15 remainder 12"

The arithmetic operations :

432 : 28 = 15 + 12

It means :

1. there are 28 rows

2. each line has 15 desserts

3. there is leftover dessert on the 29th row that only has 12 desserts

My bet is on D - 1/9 of 4 :)

I dont understand this!!! What's the answer?

Answers

The answer is 1.

4x + 3x - 1 = 6

7x - 1 = 6      -Add the like terms

7x - 1 + 1 = 6 + 1      -Add 1 to both sides to 7x by itself

7x = 7

7x / 7 = 7 / 7       -Divide both sides by 7

x = 1

Hope I helped!

To put this into words, the equation is saying that one less than 4x + 3x is equal to 6.

First simplify by combining like terms. We see there is a 4x and 3x, which means that they are compatible with each other. The equation will then look like 7x - 1 = 6. If one less than 7x is 6, then this can also mean one more than 6 is equal to 7x. So add 1 to both sides:  7x - (-1 + 1) = (6 + 1)

--> 7x = 7, which means that x = 1.

Checking your work:

Now that we know the value of x, substitute that for x in the equation like this:

4(1) + 3(1) - 1 = 6

--> 4 + 3 - 1 = 6

---> 7 - 1 = 6

So you know it's true that x = 1. Hope this was helpful.

There are 22 students on natalies class. new reading books cost $7 each. Natalies class raised $50 washing cars. If there are 2 teachers in nautiliesclass, write and evaluate an expression to show how much more each teacher will have to pay to buy the new book

Answers

22*7 = 50 + 2x  (22*7 is the total cost for all students, and the other side needs to match that cost)

evaluate:
22*7 = 50 + 2x
154 = 50 + 2x
104 = 2x
52 = x

Each teacher will have to pay $52.
Since 22 multiplied by 7 is equal to 154$ and the class has already raised 50$ you are still left with 104$ to pay . Sice there are 2 teachers you would divide 104$ by 2 and end up with 52$ .... Each teacher would have to pay 54$
