Answer:
x = 15/p
Step-by-step explanation:
4(px + 1) = 64
4px + 4 = 64
-4 -4
4px/p = 60/p
4x/4 = 60/p/4
x = 15/p
The <span>graph of y = 3/(4x-12) is decreasing sloping to the right mostly in the third quadrant whereas the graph of y = 1/x is like a mirror that is present in both quadrant 1 and 2.</span>
This is a mixture problem.
Let the 9 karat gold to be mixed be x. The 18 karat would weight (200 - x). Since the total = 200g.
mass1 * karat1 + mass2*karat = total mass * total carat
Let mass1 be x g. mass 2 would be = (200 -x)
karat 1 = 9 karat 2 = 18
Total mass = 200g.
Total karat = 14.
9*x + 18*(200 -x) = 14*200
9x + 18*200 - 18*x = 14*200
18*200 + 9x - 18x = 14*200
3600 - 9x = 2800
3600 - 2800 = 9x
800 = 9x
9x = 800
x = 800/9
x ≈ 88.89
Therefore 88.89 grams of 9 karat gold must be mixed.
Answer:
$0.75
Step-by-step explanation:
convert 5000 milligrams to grams which is 5.
Then multiply 5 by 0.15 to get the price which is 0.75
