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.
Remember, you can do anything to an equationas long as you do it to both sides
1.
-6+x=-3
add 6 to both sides
6-6+x=6-3
0+x=3
x=3
2.
add like terms
-5a+5a+9=8
0a+9=8
0+9=8
9=8

X = 50 because of the property where as long as to lines are equidistant from the center they are congruent. Since 1/2 of one side=25 and the other side is congruent you add those together to get 50 and the opposite side also equals 50
Answer: Choice B)
2x+5(2x+3) = 3
============================================
Reasoning:
We start with the second equation 2x+5y = 3
Since y = 2x+3 from the first equation, we can replace every copy of y with (2x+3). This replacement is valid because y and 2x+3 are the same.
So that's how we go from 2x+5y = 3 to 2x+5(2x+3) = 3
This replacement is done to get rid of the y variable, and it allows us to solve for x later on.
