It’s -1/3 because you subtract 1-5 and -3-9, you get -4/-12 then simplify to get -1/3.

The number of people signed up for a bus trip increased from 32 to 45. What is the percent increase? Round to the nearest percen

Lynna [10]

To calculate the percentage increase: First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100.

45-32 = 13 / 32 *100= 40.625 round to the nearest percent is 41%

What's is the answer to the equation 4(x+7)=9(x-1)+22 ?

Aleks [24]

Hello, there!

What's the answer to the equation 4(x + 7) = 9(x - 1) + 22

Answer: x = 3
------------------------------------------------------------------------------------------------------

Explanation:

First, let's simplify this
4 * x = 4x

4 * 7 = 28

Now, we have 4x + 28 = 9(x - 1) + 22

Now, let's simplify the right side by using the distributive property as well.

9 * x = 9x

9 * -1 = -9

Now, we have 4x + 28 = 9x -9 + 22

Let's combine like terms on the right side

-9 + 22 = 13

Npw, we have 4x + 28 = 9x + 13

Let's isolate the x. To do this, we will first subtract 28 from each side.

4x + 28 = 9x + 13
-28 -28

4x = 9x - 15

Now, we will subtract 9x from each side.

4x = 9x - 15
-9x -9x

-5x = -15

Now, we will multiply each side by -1 to make x a positive number.

-5x = -15
*-1 *-1

5x = 15

Finally, we will simplify this completely. To do this, we will divide each side by 5.

5x = 15
--- ----
5 5

x = 3

Our final answer is x = 3

I hope I helped!

Let me know if you need anything else!

You take a test with 32 questions and get 24 correct. What percentage of the questions did you get correct?

Marta_Voda [28]

Answer: 75%

Step-by-step explanation:

The test had 32 questions and from these 32 you were able to get 24 questions right.

The percentage of questions you got right is the percentage of 32 that 24 is.

= Number of correct questions / Total number of questions * 100%

= 24 / 32 * 100%

= 75%
