Answer: a) x/100 = 15/90x = 100(15/90)
x = (10/9)15

x = 10*(5/3)
x = 50/3
x = 16.667
x = 16% or 2/3

b)56/x=100/10(56/x)*x=(100/10)*x
56=10*x
56/10=x 
5.6=x 
x=5.6

c)180/x=100/90
(180/x)*x=(100/90)*x 
180=1.11111111111*x
180/1.11111111111=x 
162=x 
x=162

d)300/x=100/25
(300/x)*x=(100/25)*x
300=4*x
300/4=x 
75=x 
x=75

f)20/x=100/55
(20/x)*x=(100/55)*20
x=36.36
x=36

I don't know how to do e), sorry.

Determine the whether the sum of 7/8 and 4/9 is closest to 0,1,2,or 3

Answers

Whenever you add fractions it means you need a common denominator. The quickest way to find this number is to multiply the two denominators together (in this case 8 and 9).
So your new fractions are 63/72 and 32/72. When you add those you get 95/72.
Next simply divide the two numbers to get a decimal, so here we get: 1.31944...
So this number is closer to 1

How to graph 3x+1=3x+2

Answers

That equation has no graph. If it had a solution, the solution would be a single number. But that particular equation has no solution either ... there is no number that 'x' could be that would make the equation true.

After working for 24 hours,zoe made $234. After working for 40 hours, zoe made $390.predict how much she would make after 10 hours of work?

Answers

First you need to find money per hour. 234 ÷ 24 = 9.75; 390 ÷ 40 = 9.75; she makes $9.75 an hour. Multiply by ten; in 10 hours she'll make $97.5. Hope that helps!

Final answer:

To predict how much Zoe would make after 10 hours of work, we set up a proportion using the information given in the question. Cross multiplying and solving for x, we find that Zoe would make $97.50 after 10 hours of work.

Explanation:

To predict how much Zoe would make after 10 hours of work, we can use the information given in the question. We know that after working for 24 hours, Zoe made $234, and after working for 40 hours, Zoe made $390. To find out how much Zoe would make after 10 hours of work, we can use the concept of proportionality. We can set up a proportion using the number of hours worked and the amount earned:

24 hours / $234 = 10 hours / x

Cross multiplying, we get 24x = (10 * $234). Solving for x, we find that x = (10 * $234) / 24. Evaluating the expression, we find that x = $97.50.

Jack wants to know how many families in his small neighborhood of 60 homes would help organize a neighborhood fund-raising party. He put all the addresses in a bag and drew a random sample of 30 addresses. He then asked those families if they would help organize the fund-raising party. He found that 12% of the families would help organize the party. He claims that 12% of the neighborhood families would be expected to help organize the party. Is this a valid inference? No, this is not a valid inference because he asked only 30 families No, this is not a valid inference because he did not take a random sample of the neighborhood Yes, this is a valid inference because he took a random sample of the neighborhood Yes, this is a valid inference because the 30 families speak for the whole neighborhood

Answers
