Answer:

135

Step-by-step explanation:

The given expression is

\frac{2 {x}^{2} }{x} +x(100 - 15x)

From the question, x=5

So,by substitution,we obtain

=\frac{2({5}^{2})}{5} +5(100 - 15(5))

=\frac{2(25)}{5} +5(100 - 75))

=2(5)+5(25)

= 10+125

= 135

Hence the answer is 135

Answer plz. Give an explanation so I know ur not just getting points so I dont report. Thank you!
wariber [46]

Answer: A, D

Step-by-step explanation:

68 is the initial amount.

A is correct because 0.2(68) represents 20% of 68. Since you're looking for 80% of 68, you subtract 0.2(68) from 68.

D is correct because it directly takes 80% of 68, which is what the question is asking for.
