What's 500 times half of 20 then add it to the answer of 500 times the half of 20

500 X half of twenty = 5000 so add that to it's self that gives 10,000

Step-by-step explanation:

hope this helps

Example 1.   How much is a third of 120?

Answer.   Ignore the 0. Then

A third of 12 is 4.

A third of 120 is 40.

Similarly,

A third of 1,200 is 400.

A third of 120,000 is 40,000.

It is a 4 followed by four 0's.

Example 2.   How much is a third of $1.20?

Solution.  Ignore the decimal point.  A third of 120 is 40.  Now replace the decimal point.  A third of $1.20 is $.40.

Ignoring decimal points is typical in practically all problems involving decimals.  (Compare Lesson 9.)

Example 3.   How much is a fifth of $4.50?

Solution.  Ignore the decimal point.  A fifth of 450 is 90. (A fifth of 45 is 9.)  Therefore a fifth of $4.50 is $.90.

Example 4.   How much is an eighth of 4,000?

Answer.  If we ignore all the 0's, then we cannot take an eighth of 4.  But if we ignore only two 0's, then

An eighth of 40 is 5.

Therefore,

An eighth of 4000 is 500.

Decomposing

Example 5.   How much is half of 112?

Solution.  Just as we can divide by decomposing, so we can find a part of a number. We can easily decompose 112 into two numbers whose half we know:

112 = 100 + 12.

Half of 100 is 50.  Half of 12 is 6.  Therefore, half of 112 is 56.

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
