I would use a pie chart because it can show the percentage of people who like different food. It helps display the data in an easier organized way. I wouldn't use a graph because there would be too many numbers and it might be confusing when analyzing the data.
-I hope this helps! Branliest would be appreciated :)
It would reflect over the x-axis and then reflect over the y-axis
Answer:
-The equation r+b-33 represents the total number of marbles
-There 9 black marbles
-There are 24 red marbles
Step-by-step explanation:
The bag contains 33 red and black marbles. Let the number of black marbles be b and that of red marble to r
Total number of marbles will be
b+r = 33 i.e b+r-33 = 0... (1)
If the number of red marbles is 6 more than double the number of black marbles, this can be represented as;
r = 6+ 2b... (2)
Substituting 2 in eqn 1 we have;
b + 6+2b = 33
3b = 27
b = 9
r = 33-9
r = 24
This shows that there are 9 black marbles, 24 red marbles and the equation r+b-33 represents the total number of marbles in the bag.
Step-by-step explanation:
solve the equation:
5x-10=4x+20
