Answer:
I'm unsure about the first one, but the second one is irrational, the third one is option C, the fourth is option b, and the last one is D i believe
Step-by-step explanation:
Answer: (B) = 110.2
50*2.2046 = 110.23
b
since coefficient of x = 0
40 is 20% of x
40 = .2 * x
40/.2 = x
x =200
x is 80% of y
x = .8 * y
200 = .8 *y
200/.8 = y
250 =y
x+y
200+250
450
