Answer:
is it 7?
Step-by-step explanation:
I think the correct answer would be a pyramid. This is the shape where the vertex is an apex as well. The apex is the highest of a shape and the vertex is the is the point where edges meet which would be the same for a pyramid. Hope this helped.
4/5x + 4/3 = 2x....there are 2 ways to do this...one with fractions, one without.
with :
4/5x + 4/3 = 2x
4/3 = 2x - 4/5x
4/3 = 10/5x - 4/5x
4/3 = 6/5x
4/3 * 5/6 = x
20/18 = x
10/9 = x
without :
4/5x + 4/3 = 2x....multiply by common denominator of 15
12x + 20 = 30x
20 = 30x - 12x
20 = 18x
20/18 = x
10/9 = x
I'm not 100% but I think its going to be a positive answer choice.
So i would say 1/2
