Answer:
The ratio is 9:6 or 3:2 simplified.
Step-by-step explanation:
a ratio is just of many of one thing there are the the quantity of another thing. In this case, there are 9 chocolate pieces to every 6 sugar pieces. This can be written as the fraction 
and can be simplified to 
So that there are 3 chocolate pieces to every 2 sugar pieces.
The answer should be 31
(10(3)+8)-(1(3)+4)
(30+8)-(3+4)
= 31
2x + 3y = 23...........................(1)
3x - y = 7 Multiply by 3:-
9x - 3y = 21 Adding this to equation (1):-
11x = 44
x =
Plug this into equation (1):-
2(4) + 3y = 23
3y = 15
y = 5
Answer is x = 4, y = 5
Answer:
32768
Step-by-step explanation:
Each question has 2 options.
On a true/false test with one question, there are 2¹, or 2 possible answers
On a test with 2 questions, there are 2², or 4 possible answers.
On a test with 3 questions, there are 2³, or 8 possible answers.
So, 2¹⁵ = 32768 possible ways.
