"when you adjust one number and change another number in the problem to make a computation easier, you use ........... "

Answers

The compensation strategy is used in mathematics when taking the sum of two or more values in other to make computation easier.

Compensation involves adjusting the value of a certain number before processing with addition in other to make the calculation easier.

For example ; 29 + 33
We could change the value of 29 to 30 by adding 1 ; as it is easier to sum 30 and 33.
Then ; 30 + 33 = 63
The added value is then subtracted from the result.
63 - 1 = 62
Hence, 29 + 33 = 62

The above example is a simple way of using the compensation strategy.

Please help me with this! Two children had 110 marbles between them. After one child had lost half her marbles and the other lost 20 they had an equal number. How many marbles did each child start with and how many did they finish with?

Answers

An equation is a mathematical statement that is made up of twoexpressions connected by an equalsign

x + y = 110

y - (1/2)x = 20

The number of marblesonechildren had is 50.

The number of marblesotherchildren had is 60.

What is an equation?

An equation is a mathematical statement that is made up of twoexpressions connected by an equalsign.

Example:

2x + 4y = 6 is an equation.

2x + 4 is an equation.

We have,

Totalnumber of marbles = 110

Number of children = 2

Number of marblesonechildren has initially = x

Number of marblesotherchildren has initially = y

Now,

x + y = 110 _____(1)

After one child had losthalf her marbles and the otherlost 20 they had an equalnumber.

This means,

x - (1/2)x = y - 20

(1/2)x = y - 20

y - (1/2)x = 20 _____(2)

From (1) and (2) we get,

x = 110 - y _____(3)

Putting (3) in (2)

y - (1/2)x = 20

y - (1/2)(110 - y) = 20

y - 55 + (1/2)y = 20

(3/2)y = 20 + 55

(3/2)y = 75

y = (75 x 2) / 3

y = 25 x 2

y = 50

Now,

Putting y = 50 in (3) we get,

x = 110 - y

x = 110 - 50

x = 60

Thus,

The number of marblesonechildren had is 50.

The number of marblesotherchildren had is 60.

Well both children has 110 marbles between them, and one child lost half and the other lost 20 so then it said they had an equal number so the other girl must had 20 so that makes 40 and 110-40= 80 so 80 is like the marbles that are left

The sum of the squares of three consecutive positive even numbers is 12296. Find the product of the three numbers divided by 8.

Answers

Answer:

x² + (x + 2)² + (x + 4)² = 12,296

x² + x² + 4x + 4 + x² + 8x + 16 = 12,296

3x² + 12x + 20 = 12,296

3x² + 12x = 12,276

x² + 4x = 4,092

x² + 4x + 4 = 4,096

(x + 2)² = 4,096

x + 2 = 64

x = 62

The numbers are 62, 64, and 66.

(62 × 64 × 66) ÷ 8 = 32,736

when you divide a fraction less than 1 by a whole number greater than 1 is the quotient less than greater than or equal to the dividend ?

Answers

The quotient would be less than the dividend because when you divide a fraction less than 1 by a number greater than one, you are dividing a fraction by another term. Any fraction less than 1 divided by a whole number, the equation converted into a multiplication sentence would become the fraction multiplied by the term as the denominator and the numerator as a one, which a fraction multiply a fraction would be a quotient less than the dividend.

What is 5m+6+m-18=60

Answers

5m+6+m-18=60That's a linear equation in 'm '. There's only one number that 'm' can be
that makes the equation true. The assignment is usually to find out what
that number is.

Before we get carried away and confuse ourselves, let's do some work
on the left side, and try to make it simpler.

Do you see that ' 5m ' and that ' +m ' ? We can combine them, and write ' 6m '.

Do you see that ' +6 ' and that ' -18 ' ? We can combine those, and write ' -12 '.

Now the equation is much simpler:

6m - 12 = 60

Add 12 to each side:

6m = 72

Divide each side by 6 :

m = 12

5m + 6m - 18 = 60 combine like terms
11m - 18 = 60 subtract from both sides
-18 -18

11m = 78 divide 11

m = 7. 0909.....
