NEED THE ANSWER ASAP- im so confused. The sum of two numbers is 140. The second number is five more than twice the first. Find both
numbers.

Let x and y be the two numbers.

Their sum is 140, so

x + y = 140

Twice the first number x is 2x. 5 more than this is 2x + 5. This is the value of the second number, so

y = 2x + 5

Substitute this into the first equation and solve for x :

x + (2x + 5) = 140

3x + 5 = 140

3x = 135

x = 135/3 = 45

Then

y = 2*45 + 5 = 95

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%
