X + x - 8 + x/2 - 4 = 38
2x + x/2 = 38 + 8 + 4
5x/2 = 50
5x = 100
x = 20
that the amoint of water : 20
amount of rubbing alcohol: (1/2)(20-8) = (1/2)(12) = 6
difference : 20-6 = 14
hope this help
Answer: a triangle is a prism or a three angle pyramid
Step-by-step explanation:
Evey half hour for example the next time would be 9:30 then 10:30 then 11:30 and so on
He is not correct. If this is to be an equilateral triangle then all the angles must be the same measure. That means that 180/3 = 60°. They all have to equal 60°. If one of the angles measures 4x-12, then 4x-12=60. Solving for x, we will add 12 to both sides to get 4x=72. x here is 18. For the other angle measuring 2x+26, we would do the same. 2x+26=60. Subtract 26 from both sides to get 2x= 34 and x = 17. He was way off.
