Answer: The percent of people who were interested in black holes last year was 70%.

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

  • People interested in black holes this year: 62%

If the number is down from the previous year by 8%, to calculate the percent of people who were interested last year we simply have to add the 8% loss to the actual 62 %.

So, mathematically speaking:

  • 62%+8%=70%

In conclusion, the percent of people who were interested in black holes last year was 70%.

Feel free to ask for more if it´s necessary or if you did not understand something.

Answer:

22, 25, 28, 31

Step-by-step explanation:

The question is mixed up. The only clear question is:

Given:

4, 7, 10, 13, 16, 19

Required

Write the next 4

Notice that the rule of the above sequence is to "add 3". So, the next 4 numbers is gotten by adding 3 to the previous number on the sequence.

The next 4 are:

19 + 3 = 22

22 + 3 = 25

25 +3 = 28

28 + 3= 31

Which equation is equivalent to StartRoot x squared + 81 EndRoot = x + 10?
marishachu [46]

The given equation is equivalent to Option D .

The mission option is

A. x+10= x+10

B. x+9 =x² + 20x + 100

C. x² +81 = x² + 100

D. x² + 81 = x² +20x + 100

<h3>What is an Equation ?</h3>

An equation is a mathematical statement formed when two algebraic expression is equated by an equal sign .

An equation is given in the question

\rm \sqrt{x^2 + 81} = x +10

\rm {x^2 + 9^2} = (x +10)^2

\rm {x^2 + 81} = x^2 +20x + 100

Therefore the given equation is equivalent to Option D .

Write the verbal sentence as an equation:
-Dominant- [34]

Answer:

2n-12=7n-15

Step-by-step explanation:

I hope i did it right im sorry if i didnt! in the first sentence it tells you "twelve less than" therefore its telling you that you are going to be subtracting which automatically means that its not going to be the first thing you write down. You then continue reading and it tells you "2 times a number (n)" which is written as 2n because to things side by side like that signifies that you are multiplying. Then you have your equal sign which is self explanatory. and basically you follow the same reasoning as you did the first part and you end up with 7n-15 and the other half of your equation. I hope that helped!

X+9=2x-3<br> FIND THE X!!!!!!
Ierofanga [76]

Answer:

x = 12

Step-by-step explanation:

<u>To find "x"</u>, we need to <u>isolate it</u>. This means move "x" to the left side, and everything else to the right side.

When moving a number, do its <u>reverse operation</u> to the entire equation.

x + 9 = 2x - 3

x - 2x + 9 = 2x - 2x - 3         Subtract 2x from both sides

-x + 9 = -3                              

-x + 9 - 9 = -3 - 9           Subtract 9 from both sides

-x = -12

-x/-1 = -12/-1          Divide both sides by -1 to get rid of the negatives

x = 12                     Final answer

Check your answer. Split the equation for the left and right sides. Substitute "x" for the answer "12".

LS:   (left side)

x + 9

= 12 + 9              Add

= 21

RS:   (right side)

2x - 3

= 2(12) - 3            Multiply before subtracting

= 24 - 3               Subtract

= 21

Both sides equal to 21 when "x" is 12.

LS = RS          left side equals right side

Therefore the answer is correct.
