Question

Figure A is a scale image of figure B. Figure A maps to figure B with a scale factor of 2 1/2. What is the value of x? PLEASE ANSWER ASAP!!

Answer 1

`x = 2`

Explanation:

Figure B = 2½ the size of figure A

One side of figure B is given as 5, therefore, 5 = 2½ of x in figure A.

Thus,
`5 = 2(1)/(2)*x`

Solve for x

`5 = (5)/(2)*x`

`5*2 = (5x)/(2)*2`

`10 = 5x`

`(10)/(5) = (5x)/(5)`

`2 = x`

`x = 2`
