Which shows how to solve the equation 3/4x=6 for x in one step?
a_sh-v [17]

Well going off what I know (you don't have the equations up)

You have to isolate x

3/4x = 6

(4) 3/4x = 6 *multiplying by 4 cancels the fraction.

3x = 24

Divide by 3

X = 6

The three different possible conditions ;

nonalcoholic beer group, 1 beer group, 2 beer group

The Independent variable, also known as the predictor variable are variables used to influence and check changes in the dependent or predicted variable as subjects are exposed to the different types or levels of independent variable used in the study.

In the scenario described above, the predictor or independent variables which are used to measure the reaction times of participants to unexpected variables is the independent variable, beacuse these different variables ; nonalcoholic beer, 2 beer will probably affect the response time of the participants which is the dependent variable.

Make 80/6 to a mixed number explain how u got your answer
Deffense [45]

Answer:

13\frac{1}{3}

Step-by-step explanation:

The closest multiple of 6 less than 80 is 13.

13×6=78

How many are left over?

80 - 78 = 2

\frac{2}{6} remains, and this can be simplified to \frac{1}{3}

13\frac{1}{3}

Hope this helps!! (I know it sounds a little complicated but it's easy to understand it with practice :)

The conversion rates between kilograms and pounds are: 1 k g ≈ 2.2 l b s 1 l b ≈ 0.454 k g A. How many kilograms is a backpack t
denis-greek [22]

Answer:

6\ lb = 2.724\ kg

11\ kg = 24.2\ lb

Step-by-step explanation:

Given

1\ kg = 2.2\ lb

1\ lb = 0.454\ kg

Required

- Convert 6 lb to kg

- Convert 11kg to lb

To solve for (a), we make use of the second conversion unit:

1\ lb = 0.454\ kg

Multiply both sides by 6

6 * 1\ lb = 0.454\ kg * 6

6\ lb = 2.724\ kg

<em>Hence, a 6lb backpack weighs 2.724kg</em>

Solving (b): 11 kg to lb

Here, we make use of the first conversion unit

1\ kg = 2.2\ lb

Multiply both sides by 11

11 * 1\ kg = 2.2\ lb * 11

11\ kg = 24.2\ lb

<em>Hence, the cat weighs 24.2lb</em>
