Help would be nice :p *pls don't leave this qestion.....I will cry :|*Which is the best description of the equivalency of the two expressions?

Expression 1
5 x squared minus 2 x minus 4 + 6 x + 3
Expression 2
6 x squared minus 6 x + 6 minus x squared + 10 x minus 7

A.) The two expressions are not equivalent because when x = 2, the two expressions do not have the same value.

b.)The two expressions are not equivalent because when they are simplified, they do not have the same coefficients for the x squared and x terms.

c.) They are equivalent because the sum of the constants is the same in both expressions.

D.) They are equivalent because when x = 2, the two expressions have the same value.

What is 350/100 as a decimal and percent?

Answers

350/100 would convert to 3.5 as a decimal and it would be 350%. Tip: An easy way to turn a decimal to a percentage is to just move the decimal point two place holders to the right, and if there is no number in the placeholder just make it a 0.

350/100 as a decimal is 3.5 but I'm not sure about the percentage. Srry:(

The number of employees for a certain company has been decreasing each year by 6%. If the company currently has 720 employees and this rate continues, find the number of employees in 10 years.

Answers

Answer:

There will be 387

Step-by-step explanation:

This question is an example of compound decrease.

To work this out you would first have to convert the percentage of 6 into a decimal. You can do this by dividing the percentage of 6 by 100, this gives you 0.06. This is because percentages are out of 100.

The next step is to minus 0.06 from 1, this gives you 0.94. This is because we are working out the percentage decrease.

Finally to work this out you would multiply the amount of 720 by 0.94 to the power of 10, this gives you 387.80. However there can not be a decimal of a person and so it becomes 387. This is because it is working out 6% and subtracting it and then working out 6% of that new amount. This repeats 10 times.

1) Divide 6 by 100.

$6/100=0.06$

2) Minus 0.06 from 1.

$1-0.06=0.94$

3) Multiply 720 by 0.94 to the power of 10.

$720*0.94^10=387.80$

4) Round down

387

So the employees are decreasing by 6% every year.

We would represent this as: 0.06

We would represent 720 as: 720(1- .05)^0=720

So the equation would be: 720(1-0.06)^10=X
720(0.94)^10=X
720(0.53861511409)=X
387.8=X
388=X
So, after 10 years the company would have 388 employees left.
