Elliot got some new trading cards. He has 4 packs with 20 cards each. Another pack has only 8 cards. Which equation shows a way to find how many cards Elliot has in all?
c = (4 x 20) + 8
c = 4 + 20 + 8
c = (4 x 8) + 20

(4 x 20) + 8 = 88

Step-by-step explanation:

If you have 4 packs and 20 in each, you will have to multiply.

Whenever you see the word each you might have to divide or multiply

So to do this in order you will multiple first and get:

4 x 20 = 80

then he has 8 more

so just add 8

80 + 8 = 88

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%

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
