Answer:
36x + 45
Step-by-step explanation:
given
9(3x + 5 + x) ← collect like terms inside parenthesis
= 9(4x + 5)
Multiply the terms inside the parenthesis by the 9 outside
= (9 × 4x) + (9 × 5)
= 36x + 45
Answer:
28/33
Step-by-step explanation:
We first let 0.84 be x.
Since x is recurring in 2 decimal places, we multiply it by 100.
100x=84.84
Next, we subtract them.
100x−x=84.84−0.84
99x=84
Lastly, we divide both sides by 99 to get x as a fraction.
x=84/99
=28/33

Not completely sure how to answer your question but all 20 questions where worth 5 points each which she would have gotten a 100 if she got all right but she got 15 which her score would be 75. I think in a ratio of correct to incorrect would be 75:100 , I'm not sure completely.
There should be sixteen branches. There are four possible suits for the first card, hearts, diamonds, clubs, spades. Then each of those four branches has four branches for the second card drawn. 4*4 = 16.
