given is 0.65,6,8,7.9 

operation to be used 

multiplitacion subtraction and division....

0.65*8=5.20

7.9-5.20=2.7

2.7/6 = 0.45

0.85 is the weight of each pack of red beans

Okay, so you need to do substitution.

6r+8b=7.9

b=.65

6r+8(.65)=7.9

6r+5.2=7.9

6r=2.7

r=.45

Hope this helps!

*Work*

2 divided by one is 2, and 2 divided by 4 is .5

1 divided by 1 is 1, and 1 divided by 5 is .2

Add .5 + .2 and you get your answer of .7

Well, you need to find the average. You add up the hours and then multiply 15 by 8 to find out how much he gets there, then 18 by 4 for the other ammount. You add the two monotary ammounts together, then use the equation money/hours

Tada! Hope it helped.

It would be 2^11, because when multiplying the numbers, you add the exponents.

Subtract 5x from both sides

3x-2=7

Now you add 2 (Because of the negative)

3x=9

Now divide by 3 and you're done!

x=3

4

4 is the answer

(23^3)^15

(23^3)^15 = 

18956258430116202791319715713277227626159289499745290235663543 = 1.8956258430116203e61

= 1.8956258430116203*10^61

You can work that out yourself :)

Jan recieved -22 points on her exam. She got 11 wrong out of 50 questions. How much was Jan penazlied for each wrong answer? This is a division problem

C is how much she gets per correct answer and W is how much she loses for each wroing answer.

I am assuming all questions are worth the same.

This is an diaphantine equation.

Mmm I used to be able to do those ://    

I suppose you could just use trial and error. But I dso not think your question was intended to be difficult.

So once again I ask.  Do you know what she gets for each  correct answer.

39C-11W=-22

34 and 103

368

Hi Happy face :)

Do you know how much she got for her correct answer?

Yes, I know but what's the answer??? 

 14 = 3y 

Divide BOTH sides by 3 :)

112

87 and 89

Do you know what integers are?

They are whole numbers!

-6+-8

+- makes a -

-6-8

Draw a number line.

start at -6 on the number line and then go 8 more in the negative direction.
Now you tell me.  What is the answer?

-14 because two negatives equal a positive 

I really need help to answer this question, I've been working on this question for a while now ;(   10(2.2-b)=15.2

\(10(2.2-b)=15.2\)

divide both sides by 10

\(2.2-b=1.52\)

subtract 2.2 from both sides

\(-b = -0.68\)

multiply both sides by -1

\(b=0.68\)

thx
