Answer: 
Step-by-step explanation:
You need to convert from mixed number to decimal number.
In order to do this, you can follow the steps shown below:
1. You must divide the numerator of the fraction by the denominator of the fraction.
2. Now you must add the quotient obtained to the Whole number part.
Then, you get:

Then, the scale image that maps "Figure A" onto "Figure B" is:

Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure A" by
.
Therefore, the result is:

The rate a computer works is 1/time. Working together, you add the rates.
Let new computer be x, old computer be y.
x = y - 7

Rounded to nearest tenth gives:
x = 23 hours
Standard form for circle with radius r and center (h,k) is
(x-h)^2+(y-k)^2=r^2
r=36
center at -2,-7
(x-(-2))^2+(y-(-7))^2=36^2
(x+2)^2+(y+7)^2=1296

10 sqrt of 2 could be in radical form
