The difference between two number is 9 and the product of the number is 162 find the 2 number
erik [133]

Answer:

18 and 9

OR

-18 and -9

Step-by-step explanation:

Let:

first number = x

second number = y

According to given conditions:

x -  y = 9 ---------- eq1

x * y = 162 ------- eq2

From eq1:

x = 9 + y

Put it in eq2:

(9+ y)*y = 162

9y + y^2 - 162 = 0

OR

y^2 + 9y -162 = 0

By factorizing we get:

y^2 -9y + 18y - 162 = 0

Taking common:

y(y - 9) + 18(y - 9) = 0

(y - 9)(y + 18) = 0

So:

y = -18 and y = 9

ignoring negative integer

Putting values of y in eq1:

   x - 9 = 9

  x = 9 + 9

   x = 18

So the two numbers are:

18 and 9

OR

-18 and -9

i hope it will help you!

Andrew [12]

Answer:

16,876,789. 82364 ≈ 82,000

Step-by-step explanation:

Let's go through this Step by Step.

3847 * 4387 =\\3847 * 7 = 26929\\3847 * 80 = 307,760\\3847 * 300 = 1,154,100\\3847 * 4000 = 15,388,000

Now let's go through the Addition.

26929 + 307,760 = 334,689\\334,689 + 1,154,100 = 1,484,789\\1,484,789 + 15,388,000 = 16,872,789

Now, we round 82364 to the nearest thousand.

The nearest thousand is 2000. so the answer to this one would be 82000.

hope this helps.

600% as a decimal and fraction or mixed number
OleMash [197]
Hello there!

Decimal

To convert a percentage to decimal, you move the decimal point 2 places to the left. 600% - 6.0

Fraction
To convert a percentage to a fraction, divide the percentage by 100. 600/100 = 6/1 = 6

Hope this helps! :)
