Hello!

A. You can see that 6mm is equivalent to 12mm since 6 X 2 = 12 you can assume that 10mm is equivalent to x = 20mm.

B. Be careful, the triangles are not in the order of the statement. 3mm is equivalent to 39mm so you divide 39 by 3 to get 13, in other words, triangle NOP was enlarged 13 times (3mm X 13 = 39mm) to get triangle XYZ. Then you multiply 7 by 13 to get “w,” 7 X 13 = 91mm. So w = 91mm, in other words, triangle NOP was enlarged 13 times (7mm X 13 = 91mm) to get triangle XYZ.

I hope this helps!

Answer:

The next one  3/7 = 39/w   so 39 x 7 = 273  divided by 3  = 91    so w = 91

Explanation:

Set up ratios to solve.  the first one  the 12 corresponds to the x ad the 6 corresponds to the 10   , so  12/6  =  x/ 10   .   use cross products, you might call it butterfly math,   12 x 10 = 120  divided by 6  so x = 20.
