Match the justification to each statement in the solution of x + 12.7 = -25.2.

1) x+12.7=-25.2 is given

2)x+12.7-12.7=-25.2-12.7 is the subtraction property of equality(subtracting on both sides)

3)x+0=-37.9(add. inverse/simplification since we're simplifying the equation)

x=-37.9(identity property of addition since x+0 is just x)

Hope this helps!

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

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.
