Solve the equation using the distributive property and properties of equality.
-5(a+3) = -55
what is the value of a?

a -14

b -8

c 8

d 14

C) 8

Step-by-step explanation:

The Distributive property says a(b+c)=ab+ac, using this knowledge, follow the steps provided below to solve the problem :)

1) Distribute -5 to a and 3:

-5a-15=-55

2) Add 15 to both sides:

-5a=-40

3) Divide both sides by -5:

a=8

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.

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
