Answer: Let's say 'x' to the unknown length, since the sides are proportional we can build up a equation like this : \frac { 11 }{ 8 } =\frac { x }{ 12 } \n 11\cdot 12=8x\n 132=8x\n \frac { 132 }{ 8 } =x\n x=16.5 
The answer is A.

The answer would be 10, because 5/5 is a whole fraction so it is technically 1.So the real problem is what is 1*10 and that = 10
So,

There are two (or more) ways to solve this.

#1: We can notice the pattern as the numerator goes up by 1 each time.

Every time the numerator goes up by 1, the result goes up by 2.  Since the previous item was worth 8, and since the number we are trying to find is obviously the next item in the series, we can just add 2 again to get 8 + 2 = 10.  So 10 is your answer.

#2: We can recognize that 5/5 is equal to 1.

Since 5/5 is equal to 1, and anything multiplied by 1 remains the same, we can say that 1 * 10 = 10.  So 10 is still your answer, without so much brain-work.

Ayesha has a theory about two digits numbers that have a larger tens digit then ones digit.she says that reversing the digits and subtracting the reversed number from the original number will always generate a number that is multiple of 9.is ayesha right?if so why do you think this works?if not,why not?

Answer:

Yes she is right

Step-by-step explanation:

Given that Ayesha has a theory about two digits numbers that have a larger tens digit then ones digit.she says that reversing the digits and subtracting the reversed number from the original number will always generate a number that is multiple of 9.

The reason is as follows: Let x be in 10th digit and y be in unit digit.

x>y

10x+y will be the place value.

If reversed we have 10y+x would be the value of the number

Difference would be

10x+y-(10y+x)\n=9x-9y\n=9(x-y)

Hence this has to be a multiple of 9.

Yes she is right. It works because the sum of the individual digits of the difference is divisible by nine.

What is the equation of the graphed line? Hint: Determine the slope of the line =  x .

Answers

y=-5x

you can use point slope or slope intercept to find this one. i did it by using slope intercept, y=mx+b
b in this case is 0, and then to find m you use (y-y)/(x-x) or (-5-0)/(1-0) = -5
