Answer: [tex]x=21.75[/tex]
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:
[tex]7\frac{1}{4}=7+0.25=7.25[/tex]
Then, the scale image that maps "Figure A" onto "Figure B" is:
[tex]1:7.25[/tex]
Finally, in order to find the value of "x", you need to multiply the given length of the corresponding side of "Figure A" by [tex]7.25[/tex].
Therefore, the result is:
[tex]x=(3)(7.25)\\\\x=21.75[/tex]
