subtract 3x from both sides:-

-(1/4)y = -3x - 2

Write an algebraic expression for 15 decreased by twice a number

Answers

15-2x= that would be the algebraic equation. Remember that decrease usually means minus. A number is always represented by a variable, and then anything that by is usually a multiplication or division depending on how its stated.
An algebraic expression is, obviously, an expression with a variable.

"A number" would represent a variable, which, in this case, we'll use y.

So, 15 decreased by twice x.
15 - y x 2 =

Write each fraction as a percentage

Answers

Hi there!

To convert a fraction to a percentage you need to first convert the fraction to a decimal number. To convert a fraction to a decimal number you need to treat the fraction like a division problem.

(1)/(3) as a division problem would be 1 divided by 3, which is:

1 ÷ 3 = 0.3333333...

Now to covert a decimal to a percent all you do is move the decimal point over to the hundreds place, so it will look like this:

33.3

I will be rounded down because it is less then 5. Now just add a percent sign on the end and that is your answer! I should look like this:

33.3%

Your friend, ASIAX
1.3 I think cause that's a percentage

What is 7,491,001 rounded to the nearest hundrer thousand

Answers

Answer:

7,491,001 --> 7,500,000

Step-by-step explanation:

This is because rounding happens like this:

The rounding rule is: 5 and above rounds up, and 4 and under rounds down.

Here is a little rhyme for the rule: 5 and above rounds up like a dove. 4 and below, get down low!

7,491,001

--> you want to round the underlined digit. You round using the next digit to the right. The next digit over is the 9. Remember our rounding rule. Since 9 is above 5, the 4 would round up. Note - the digits after the rounded number always become zeros, even if you round up or down. So our new number is 7,500,000.

I hope I helped!
