Answer:
x=0
Step-by-step explanation:
7/2x+6/4x=5/4x
7/2x=5/4x-6/4x
7/2x=-1/4x
7/2x-(-1/4x)=0
7/2x+1/4x=0
14/4x+1/4x=0
15/4x=0
x=0/(15/4)
x=0
It's 28 5/7. 10 +18 and 2/7 + 3/7
You can try with : 30 x 40 x 10. Volume is 12000 and the surface area:
2*30*40 + 2*30*10 + 2*40*10 = 2400 + 600 + 800 = 3800. This is a surface area between 3200 cm² and 4000 cm².
The number could be 250. The reason why is because 1250 divided by 5 = 250, and 250 divided by 5 = 5. Hope this helps you, and good luck!!
