Answer:
x=27 and NL = 40
Step-by-step explanation:
by properties of secants starting from common point-
LK x LJ = LM x LN
10 * (10+42) = 13 * (13+X)
X = 27
To find k, divide both sides by 1/4
K = 2/3 / 1/4
When dividing by a fraction flip the second fraction over then multiply:
K = 2/3 x 4/1 = (2 x 4) / (3 x 1) = 8/3
K = 8/3 = 2 and 2/3
The amount of paint used is <u>8.4 litres</u>.

EXPLANATION</h3>
To work this out, you need to<em> times 1.2 by 7</em>, to get the answer of <u>8.4 litres</u>.
Hope this helps!
Answer Using the method of alligation. 40.0= 20/(10/20) qts of 50% solution to add to your 20 qts of 20% solution. 60.0= (20+40.0) qts of the final 40% solution.
