To solve the system of linear equations 8x+ 5y - 18 and 6x+y --2 by using the linear combination method, Amos decided
that he should first multiply the second equation by -5 and then add the two equations together to eliminate the y-terms.

The answer is A.

Trust me, I got it right

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
