Answer:

x=3.76 (3.7 recurring rounded to 2 decimal places)

x= \frac{34}{9}

Step-by-step explanation:

You follow the simple steps of finding the value of a variable in an equation by doing PEMDAS/BOMDAS backwards

6(\frac{3x}{2}-4)=30

6(\frac{3x}{2}-4+4)=30+4

6(\frac{3x/3}{y})=\frac{34}{3}

6(2\frac{x}{2})=2\times11.3  recurring

\frac{6x}{6} = \frac{22.6}{6}

x=3.76\\x=\frac{34}{9}

*Brainliest*<br> I need help with 4 problems like this...KHAN ACADEMY.
Sedaia [141]

Answer:

  1. (x +1)² = 4
  2. (D)  x = -1 ±2

Step-by-step explanation:

Start by getting the x-terms on one side of the equal sign. We can do that by subtracting x from both sides.

  3 = x² +2x

Now, add the square of half the x-coefficient.

  3 +1 = x² +2x +1

  (x +1)² = 4 . . . . . . . . write as a square in the desired form

__

To solve, take the square root, and add the opposite of the left-side constant.

  x +1 = ±2

  x = -1 ±2 . . . . . . matches choice (D)

I need to solve this to get zero can you help?
Alex

Given a right triangle with the side lengths of legs = 9 and 13

For the required angle :

opposite side = 9

adjacent side = 13

so,

\begin{gathered} \tan \theta=\frac{opposite}{adjacent}=\frac{9}{13} \\  \\ \theta=\tan ^{-1}\frac{9}{13}=34.7 \end{gathered}

Use the circle graph to determine how many hours per day Becky spends on each activity.
Oduvanchick [21]
404 error: graph not found

anyway, the graph was not included. since the sleep time was included, I will assume that the circle graph is worth 24 hours

all we need to do is to convert the percentages to fractions and multiply that by 24 to find out how many hours per activity


percent means parts out of 100 so x%=x/100


so we have
School
Eating
Sleep
Homework
Free Time

School=25%
25%=25/100=1/4
1/4 times 24=6
School: 6 hours


Eating=10%
10%=10/100=1/10
1/10 times 24=2.4
Eating: 2.4 hours


Sleep=40%
40%=40/100=4/10=2/5
2/5 times 24=48/5=9.6
Sleep: 9.6 hours


Homework=10%
10%=10/100=1/10
1/10 times 24=2.4
Homework: 2.4 hours


Free Time=15%
15%=15/100=3/30
3/20 times 24=72/20=36/10=3.6
Free Time: 3.6 Hours

Answers:
School: 6 hours
Eating: 2.4 hours
Sleep: 9.6 hours
Homework: 2.4 hours
Free Time: 3.6 Hours
