Answer:
First, assign a value to x.<em> x</em> will be 2 in this case.
Next, multiply x by itself, because that is what exponent 2, or squared, means. 2 x 2 = 4
Now, multiply 4 by 7. 4 x 7 = 28
Next, find the value of <em>9x</em>.
The value of 9x will be 9 times a number, x, also known as 2 in this scenario. 9 x 2 = 18
Then, subtract 28 from 18. 28 - 18 = 10
Lastly, subtract 10. 10 - 10 = 0
Therefore,
The answer is 0. <em>Product may vary depending on value assigned to x.</em>
It is asking what 7/8 of 2/3 is. The "of" means you need to multiply. 7/13 is the answer.

Answer:
14 is A
15 is B
Step-by-step explanation:
14 . the answer is a because first off the slope is negative so we can immediately eliminate B and D second of all the slope is 1/2 so we can eliminate D and get that the answer has to be a
15. answer is B for this one because first of all the slope is negative so we can immediately eliminate A and c and second of all the y-intercept would be 120 because 90 is what x=1 so we would have to add 30 to get what y would equal when x=0 if that makes sense
Answer:
Half a block ( 0.5 or 1/2 )
Step-by-step explanation:
8 1/2 blocks can also be written as 8.5 blocks.
If Kira walks 8.5 blocks in 17 minutes [and continues to walk at this steady pace], divide 8.5 by 17.
8.5/17 = 0.5
So, Kira walked 0.5 or 1/2 blocks in a minute.
I hope this helps! :)
