what is the answer of =
(+2) - (-5) = ?

7

Step-by-step explanation:

2-(-5)=7

(2) + (5)

Step-by-step explanation:

Whenever you change the sign you also change the second number in the expression, in this case, (-5) has to be changed into (5) because you change the - sign to a + sign.

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.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1
