Answer:
X = 17.5
Step-by-step explanation:
Here we have a word problem relating to syntax regarding mapping of a scale factor;
Whereby the scale factor is 3.5 we have that the scale factor can be represented as 2:7
Hence the scale is for every 2 units of Figure A, we have 7 units of Figure B
Hence where Figure A is 5, we have;
2 unit of Figure A = 7 units of Figure B
∴ 1 unit of Figure A = 7/2 (=3.5) units of Figure B
5 unit of Figure A = 3.5 × 5 units of Figure B = 17.5 units of Figure B
Therefore where we have;
5 unit of Figure A = X units of Figure B
Then, X = 17.5.
