In 11 years, John's age will be 5 less than 5 times his current age. How old is he? If x represents John's current age, which of the following equations could be used to solve this problem? x + 11 - 5 = 5x x + 11 = 5x - 5 x + 11 = 5 - 5x

Step-by-step explanation:

Let John's age be x. This gives us that in 11 years, john's age will be 5 less than 5 times his current age. Therefore, we could get: . This is your second equation. Solving for x, we get 4x=16 so x=4.

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%

the square root of what number? if you add that, then someone will probably answer the question.
