\bold{Answer}

\boxed{\bold{X \ = \ -10}}

\bold{Explanation}

  • \bold{Simplify: \ -\frac{3}{4}\left(x+2\right)=6}

\bold{-------------------}

  • \bold{Multiply \ Both \ Sides \ By \ -4}

\bold{\left(-\frac{3}{4}\left(x+2\right)\right)\left(-4\right)=6\left(-4\right)}

  • \bold{Simplify}

\bold{3\left(x+2\right)=-24}

  • \bold{Divide \ Both \ Sides \ By \ 3}

\bold{\frac{3\left(x+2\right)}{3}=\frac{-24}{3}}

  • \bold{Simplify}

\bold{x+2=-8}

  • \bold{Subtract \ 2 \ From \ Both \ Sides}

\bold{x+2-2=-8-2}

  • \bold{Simplify}

\bold{X \ = \ -10}

\boxed{\bold{Eclipsed}}

-10.

Solution: Multiply the negative three fourths by everything in the parenthesis.

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

Add the negative three halves to both sides.

-  \frac{3}{4} x  =  \frac{15}{2}

Multiply both sides by negative four thirds.

x =  - 10

20 is what percent of 52
Maslowich
The process here is finding out the smallest number's % towards the largest number.

Divide 20 by 52:
20/52 = 0.38 (estimated) | This is the % in decimal form, which is 38%.

Conclusion: 20 is 38% of 52.

{---Further Elaboration for Future Reference---}

Finding the Smallest Number:

What number is 25% of 60?

Multiply 60 by the decimal form of 25%.
60 * 0.25 = 15 | 15 is 25% of 60.

Finding the Percentage. (Like what we already did.)

30 is what percent of 150?

Divide 30 by 150.
30/150 = 0.2 | 30 is 20% of 150.

Finding the Largest Number.

12 is 30% of what number?

Divide 12 by the decimal form of 30%.
12/0.3 = 40 | 12 is 30% of 40.

I hope this helps, have a great rest of your day! ^ ^

Use +,-,x, ÷ and parentheses to connect the numbers 1,3,5 and 7 such that the result is 24.
Alborosie

Answer: (3-1)×(7+5)

Step-by-step explanation:

There are mainly several ways to get 24

- 2×12

- 3×8

- 4×6

- add all of them together

- complicated ones can include large numbers minus another large number

Use try-check-revise, to find the way that fits 24

For this question, we used 2×12, which results in (3-1)×(7+5)

Hope this helps!! :)

Please let me know if you have any questions.

The table represents the change in the boiling point of water at different altitudes. Altitude (in thousands of feet) Boiling Po
Anton [14]
Answers:

1) The dependent variable is the boiling point of water and the independent variable is the altitude.

2) The slope would represent the average decrease of the boiling point of water per every one thousand feet that the altitude increase.

Explanation:

1) given

Table:

<span>Altitude (in thousands of feet)    Boiling Point of Water (Fahrenheit)

(sea level) 0                                212
0.5                                               211.1
1.0                                               210
2.0                                               208.4
2.5                                               207.5
3.0                                               206.6
4.0                                               204.8
4.5                                               203.9

2) The independent variable is the input of the function, and the dependent variable is the output of the function.

The input determines the output once the rule is established.

Therefore:

a) the independent variable is the altitude, and
b) the dependent variable is the boiling point of water in Farenheit.

3) The slope of the graph would be:

                 change in the dependent variable          change in boiling point
slope = --------------------------------------------------- =  ---------------------------------
</span>                 change in the independent variable          change in altitude

Therefore, the slope represents the average change in the boiling boilin point of water every one thousand feet on change of altitude.

If the relationship is not linear, then the slope is not constant, and you will have different slopes for different parts.

If the slope is negative, means that as the altitude increase the boiling point of water decrease.

You can calculate the slope using any two pair of points (data)

              212 - 210           2
slope =---------------- =   ------- = - 2
                0 - 1            - 1

or, using other pair of points:

                204.8 - 210           -5.2             
slope = --------------------- =   --------- = -2.6
                  4.0 - 2.0               2.0

As you see, the slope is not constant. So, the function is not linear.
