Answer:
when you have two fractions that equal each other you want to solve by using cross multiply
What cross multiply is, is when you multiply diagonally so:
8/x=14/7
you would take 14*x and 8*7
14x=56 (you would then divide each side by 14)
x=4 (14/14=1, 56/14=4)
8/4=14/7
To check your work you could simplify
8/4=2
14/7=2
2=2, which is true
x=4
Hope this helps ;)
Answer:
I think it is right but not sure
When x=1 and -2 so it is C
Un decimal que es 1/10 de 3,0 es 0,3
All of the above. it is a three dimensional pyramid, and a "polyhedron" means it is triangular.
