Answer:
x = -11/5 and y = 24/5
Step-by-step explanation:
Use elimination.
First, we need to multiply so that at least one variable can cancel out.
We can multiply the top equation by 2.
So we get
4x + 6y = 20
Then, we can use elimination.
The x's cancel out.
So we get 5y = 24
Or y = 24/5
Then, we can plug in this y value back into the first equation to find x.
2x + 3(24/5) = 10
2x + 72/5 = 50/5
2x = -22/5
x = -11/5
So x = -11/5 and y = 24/5
Answer:

Step-by-step explanation:
-Probability is the likelihood of an event occurring.
-The total number of events is:

-The total number of blue events is:

#Probability of a blue is thus calculated as:

Hence, the probability of choosing a blue marble at random is 37.5%
Answer:
C. 3 cans
Step-by-step explanation:
9 1/9 times 3 is 27.33 and if one can cover 10 square meters then that means you'll need 3 cans.
