Answer:

x=6

Step-by-step explanation:

<u><em>first thing first you always need to get x alone and since you have an X on both side we need to move one of them to the same side as the other one.</em></u>

8x-72=2x-36

add 72 on both sides ( the opposite of subtracting is adding)

8x=2x-36+72  

8x=2x+36

then we subtract 2x on both sides to get X alone

8x-2x=36

6x=36

then we divide 36 by 6 to get our answer for x

X= 6

and that's your answer, hope this helped

Answer: x=6

<u>Subtract 2x from both sides</u>

<u></u>8x-72-2x=2x-36-2x\\6x-72=-36<u></u>

<u></u>

<u>Add 72 to both sides</u>

<u></u>6x-72+72=-36+72\\6x=36<u></u>

<u></u>

<u>Divide both sides by 6</u>

<u></u>6x/6=36/6\\x=6<u></u>

Kaylis [27]

Answer:

The angles inside a hexagon add up to 720.

105 + 88 + 142 + 140 + 124 + x = 720

720 - (105 + 88 + 142 + 140 + 124)  = x

720 - 599 = x

<h2>x = 121</h2>

At an output level of 50 units per day, a firm has average total costs of $60 and average variable costs of $35. Its total fixed
e-lub [12.9K]

Answer:

$ 1250

Step-by-step explanation:

output = 50 units per day

average total cost = $ 60

total cost = output × average total cost =50 × 60 = $ 3000

total variable cost = output × average variable cost = 35 × 50 = $ 1750

total cost = total fixed cost + total variable cost

total fixed cost = total cost - total variable cost = $ 3000 - $ 1750 = $ 1250

A box contains 15 resistors. twelve of them are labelled 50ω and the other three are labeled 100ω. what is the probability that
Igoryamba

Answer : P(second resistor is 100ω , given that the first resistor is 50ω) is given by

\frac{1}{5}

Explanation :

Since we have given that

Total number of resistors =15

Number of resistors labelled with 50ω = 12

Number of resistors labelled with 100ω =3

Let A: Event getting resistor with 50ω

B: Event getting resistor with 100ω

Since A and B are independent events .

So,

P(A\cap B)=P(A).P(B)

Now, According to question , we can get that

P(A)= \frac{12}{15}=\frac{4}{5}\\\\P(B)=\frac{3}{15}=\frac{1}{5}

So,

P(A\cap B)=P(A).P(B)\\\\P(A\cap B)=\frac{4}{5}\times \frac{1}{5}\\\\P(A\cap B)=\frac{4}{25}

So, by using the conditional probability , which state that

P(B\mid A)=\frac{P(A\cap B)}{P(A)}

P(B\mid A)=\frac{\frac{4}{25}}{\frac{4}{5}}\\\\P(B\mid A)=\frac{5}{25}\\\\P(B\mid A)=\frac{1}{5}

So, P(second resistor is 100ω , given that the first resistor is 50ω) is given by

\frac{1}{5}
