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>

Use the graph to complete the following. The probability that a boxer weighs between 60 and 80 pounds is %
AlexFokin [52]

Answer:

95%

Step-by-step explanation:

The Empirical rule, also the 68–95–99.7 rule, states that for a population that is approximately normal or symmetrical, nearly all of the data values will lie within three standard deviations of the mean;

68% of data values will fall within one standard deviation from the mean

95% of data values will fall within two standard deviation from the mean

99.7% of data values will fall within three standard deviation from the mean

From the graph given, we note that the weights 60 and 80 pounds fall within two standard deviations from the mean;

70 ± (2*5) = 70 ± 10 = (60, 80)

70 is the mean, 5 the standard deviation and 2 the number of standard deviations from the mean. From the Empirical rule we can conclude that the probability that a boxer weighs between 60 and 80 pounds is 95%

Andrew is paid $4 per hour for the first 30 hours he works each week. He makes $5 per hour for each hour he works over 30 hours
klasskru [66]

Answer:

If Andrew works for 30 for $4 he will have a total wage of 30×4=$120

And gets additional $5for every hr worked beyond 30hrs in that week

So he gets a total of 5(x-30)

So if he works for 40hrs he gets a total wage of

5(40-30)=50

120+50=$170

If he works for 50 hours he gets Total wage of

5(50-30)=100

120+100=$220
