x=4
Step-by-step explanation:
tangent lines from the same point to a circle are congruent in length, so we can say that
5x+8 = 8x-4
5x -5x +8 = 8x - 5x -4
8 = 3x - 4
8+4 = 3x -4 + 4
3x = 12
3x/3 = 12/3
x=4

Answer:
Step-by-step explanation:
Set this up as a proportion with the ratios being
If there is a 2:5 ratio of vinegar to oil, that ratio looks like this:
and if we are looking for how much oil, x, is needed for 20 ml of vinegar, then that ratio completes the proportion:
and cross multiply.
2x = 100 so
x = 50 ml of oil
