Do the top , been trying for hours to solve

2x+30

Step-by-step explanation:

The perimeter of a rectangle is

P = 2(l+w)

The length is 2/3 x+10  and the width is 1/3x +5

P = 2(2/3x +10 + 1/3x +5)

Combine like terms

P = 2(2/3x + 1/3x +10+5)

   = 2(x +15)

Distribute the 2

   = 2x+30

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.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
