Answer:

x = 22-8 option(D)

Step-by-step explanation:

The given equation is x+8=22

x+8=22

We can solve the above equation by hit and trail or by using transformation

put different values of x, we get x= 14

By transformation method,

+8 will go to right hand side and converted into -8

x=22-8

x=14

Hence, option (D), x=22-8 is correct.

I'm not entirely sure but I believe it would be 8=22-x because x=16 so 8 does equal 22-16

brilliants [131]

Answer:

x = 5

Step-by-step explanation:

Given

13 = - 7 + 9x - 5x , that is

13 = - 7 + 4x ( add 7 to both sides )

20 = 4x ( divide both sides by 4 )

5 = x

Answer:

Step-by-step explanation:

Given that a study of 250 households in Cedar Bluff showed that a household produced an average of 4 pounds of garbage per day.

Here a study of only 250 were made to assess about the entire households in Cedar Bluff

Hence the population of interest in this study is the entire households in Cedar Bluff.

The sample is the 250 households in Cedar Bluff which were studied

The objective was to study the sample and from that information to assess about the population.

The total resistance in a circuit with two parallel resistors is 2 ohms and R1 is 6 ohms. Using the equation for R2, in terms of

ivanzaharov [21]

<h2>Answer:</h2>

$R_2$ is 3 ohms

<h2>Step-by-step explanation:</h2>

In a circuit containing two resistors $R_1$ and $R_2$ connected together in parallel, the total resistance $R_T$ is given by;

$\frac{1}{R_T} = \frac{1}{R_1} + \frac{1}{R_2}$ ---------(i)

<em>Make </em> $R_2$ <em> subject of the formula;</em>

=> $\frac{1}{R_2} = \frac{1}{R_T} - \frac{1}{R_1}$

=> $\frac{1}{R_2} = \frac{R_1 - R_T}{R_TR_1}$

=> ${R_2} = \frac{R_TR_1}{R_1 - R_T}$ ---------------(ii)

From the question,

$R_1$ = 6Ω

$R_T$ = 2Ω

Substitute these values into equation (ii) as follows;

=> ${R_2} = \frac{2*6}{6 - 2}$

${R_2} = \frac{12}{4}$

$R_2$ = 3Ω

Therefore, the value of $R_2$ = 3 ohms or $R_2$ = 3Ω

Find the roots. 2x ^2 + 4x - 5 =0

Vinvika [58]

Literally the roots equal 0. Is that “X” or the multiplication sign? Because I did it with “X” and it gave me “0”
