2−(x−10)=5x
what is x?

Answers

Answer 1

Answer:

2

Step-by-step explanation:

2−(x−10)=5x

Step 1: Simplify both sides of the equation.

2−(x−10)=5x

2+−1(x−10)=5x(Distribute the Negative Sign)

2+−1x+(−1)(−10)=5x

2+−x+10=5x

(−x)+(2+10)=5x(Combine Like Terms)

−x+12=5x

−x+12=5x

Step 2: Subtract 5x from both sides.

−x+12−5x=5x−5x

−6x+12=0

Step 3: Subtract 12 from both sides.

−6x+12−12=0−12

−6x=−12

Step 4: Divide both sides by -6.

−6x−6=−12−6

x=2

Answer:

x=2

Answer 2

Answer:

x = 2

Step-by-step explanation:

2-(x-10) = 5x

distribute the - into the  (  )

2 -x + 10 = 5x

combine like terms

12 - x = 5x

     +x    +x

12 = 6x

divide both sides by 6

x = 2

Hope this helps!!!

Classify √3.
√3 means "the nonnegative square root of 3."
The square root of a number is a number that when multiplied by itself equals the original number. The radical symbol √ is used to denote the nonnegative square root.
​

Answers

√ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.

We are given a number √ 3.

We need to classify the number.

First we can see that, this is the non negative square root of the number 3.

That is when we multiply √ 3 two times, we get the number 3.

Also, we can see that, it will be an irrational number as it will be non terminating and non repeating number.

That is it will be a real irrational number.

Therefore, we get that, √ 3 can be classified as a non negative square root of the number 3 which is also a real and irrational number.

Lola's puppy weighed 19 ounces on the second visit the puppy had gained 9 ounces on the third visit the puppy heaven gained another 7 ounces what is the percent increase since the first visit and the puppy weighed around to the nearest percent

Answers

Answer:

84%

Step-by-step explanation:

In order to calculate this, we first need to calculate the total weight of the puppy on the last visit. We do this by adding the weight that the puppy gained each visit like so...

19oz + 9oz + 7oz = 35oz

Now that we have the final weight we simply divide the final weight by the initial weight of the puppy in the first visit. Then we subtract 1 from that value and multiply by 100 to get the percentage increase.

35oz / 19oz = 1.84

1.84 - 1 = 0.84

0.84 * 100 = 84%

Finally, we can see that the puppy had an 84% increase since the first visit.

The points (-5, 5) and (5, r) lle on a line with slope -3. Find the missing coordinate r.

Answers

Answer:

r = -25

Step-by-step explanation:

slope is change in "y" over change in "x"

so whatever your change in "x" is between the two points, the change in "y" needs to be in proportion to the slope of -3.

Here the change in "x" is +10, and to make the proportion of the slope equal to -3, the change in "y" needs to be -30.

Starting from the "y" coordinate of 5, a change in "y" of -30 will give you r = -25

So the two points are (-5, 5) and (5, -25)

The total number of tickets given away is 280

How to determine the total number of tickets?

To do this, we make use of the following representations:

c represents childrena represents adultss represents senior

From the question, we have the following equations:

a = 20 + c --- 20 more adult than children

s = 3a ---- 3 times as many senior as adult

c = 40 --- number of children tickets

Substitute c = 40 in a = 20 + c

a = 20 + 40

a = 60

Substitute a = 60 in s = 3a

s = 3 * 60

s = 180

The total number of tickets is:

Total = a + c + s

This gives

Total = 60 + 40 + 180

Evaluate

Total = 280

Hence, the total number of tickets given away is 280
