Answer:

The Answer is: x=10 or anything less than 10, but if there are no answer choices, I recommend you just say 10 or under 10

Step-by-step explanation:

2/3(3x-6)+1 = 15=

(2x-4)+1 = 15 =

(2x-5) = 15 =

(2x) = 20 =

x = 10 or less

Its kinda complicated, first ignore the less than or greater than sign and change it to an equal to sign now simplify it by doing order of operations, normally parenthesis goes first but there's nothing you can do in there, so since its 2/3(3x -6), you will need to divide everything in the parenthesis by 2/3, subtract everything by a third of its amount, and your outcome will be (2x  -4) + 1, now add the one to 4 and you will now get 5 and your new outcome will be (2x-5) = 15. Now that its simplified instead of subtracting the 5 you will be adding it to the opposite side, which sounds complicated so let me explain, since you can't simplify it further, your basically summing it up on the opposite side therefore, with this, you will get (2x) = 20, same goes with multiplication too, you sum it up on the other side by its opposite, which is division, so instead of multiplying 2 by x, your dividing 20 by 2, and you will get as your new outcome, and your answer x = 10 or of which less than 10 because 10 is greater than or equal to x.

Therefore, your final answer is x is less than or equal to 10.

Hope This Helps!

In a survey, 200 people were asked if they smoke and whether or not they exercise regularly (more than twice a week). The result
siniylev [52]

Answer/Step-by-step explanation:

a. % of people who smoke = no. of people who smoke ÷ total no. of people surveyed × 100

Total no. of people who smoke is given = 4 + 36 = 40

Total people surveyed = 200

% of people who smoke = \frac{40}{200}*100 = \frac{40}{2}*1 = 20 percent

a. % of people who do not exercise regularly = no. of people who do not exercise regularly ÷ total no. of people surveyed × 100

Total no. of people who do not exercise regularly = 36 + 134 = 170

Total people surveyed = 200

% of people who smoke = \frac{170}{200}*100 = \frac{170}{2}*1 = 85percent

Write your own explicit formula. List the first 4 terms and solve for the 10th term using the formula. (show your work)
Shalnov [3]

Answer:

See below.

Step-by-step explanation:

Formula:

a_n = 3(n + 4)

First term: n = 1

a_1 = 3(1 + 4) = 15

Second term: n = 2

a_2 = 3(2 + 4) = 18

Third term: n = 3

a_3 = 3(3 + 4) = 21

Fourth term: n = 4

a_4 = 3(4 + 4) = 24

Tenth term: n = 10

a_{10} = 3(10 + 4) = 42

Name the angle pair relationship and solve for the given angle
Natasha_Volkova [10]

Answer:

The angle (7x-14) and (4x+19) are corresponding angles. Both angles are 63 degrees.

Step-by-step explanation:

Since the two angles are corresponding, they are equal.

7x-14 = 4x + 19

Subtract the 4x on right side to get 19 alone. Do the same on the left side since, whatever you do on one side, you have to do to the other.

3x-14 = 19

Add the -14 on the left side to get 3x alone. Do the same on the right side since, whatever you do on one side, you have to do to the other.

3x = 33

Divide by 3.

x = 11

Judges in a diving competition gave scores of 9.3, 9 1/2, 9 4/5, 9.95 And 9 1/4. Which two scores were closest to one another?
Kazeer [188]

9.3 and 9\frac{1}{4} were closest to another.

<u><em>Explanation</em></u>

First we will convert each given fractions into decimal form. So....

9\frac{1}{2}= 9+\frac{1}{2} = 9+0.50 =9.50\\  \\ 9\frac{4}{5}= 9+ \frac{4}{5}= 9+0.80=9.80\\   \\ 9\frac{1}{4}= 9+\frac{1}{4} =9+0.25= 9.25

Then the scores are: 9.30, 9.50, 9.80, 9.95 and 9.25

So, 9.30 and 9.25 are closest to another as their difference is (9.30-9.25)=0.05

That means , 9.3 and 9\frac{1}{4} were closest to another.
