Step-by-step explanation:
x+40%x=50%×480ml
x being 100% alcohol
14x=240ml
x=120/7 ml
x=17.(142857) ml
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 10 to both sides
-6 (+10) = n/2 - 10 (+10)
10 - 6 = n/2
4 = n/2
Next, isolate the n. Multiply 2 to both sides
4(2) = n/2(2)
n = 4(2)
n = 8
8 is your answer
hope this helps

I don't know if you have heard of this question but if you
Well, first, we can conclude that Arc KJ is equal to Arc GH. Add those for 144. Subtract from 360 and divide that answer by 2 to get the arcs of JH and KG. They are 108. The second is 108. Now we can conclude that the triangles are congruent. We can subtract 54 from 90 to get the rest of angle KGH. That would be 36. We can add the angles to figure out that angle H is 90, since 54 and 36 make 90 and subtract from 180. GJH would be 36 since we found out the 90 and 54.
