Answer:
if Y = 2x so place 2x to the why and for it can = 12 well put 10x
Answer:
x=19.3333
Step-by-step explanation:
Cross multiply
6(x-3)=14*7
6x-18=98
6x=98+18
6x=116
x=19.3333
I think its D but im not 100% sure let me know if its right
Answer:
4 maybe
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
All the triangles are similar, so ...
... 3/y = y/27 . . . . . ratio of short side to long side
... 81 = y² . . . . . . . . multiply by 27y
... 9 = y
The Pythagorean theorem tells you ...
... z² = 3² + 9² = 9 +81
... z² = 90 = 9·10
... z = √(9·10) = 3√10
