Answer:
x= -3
y= -2
From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.
Answer:
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25. The second useful rule is the Sum Rule.
First find the hourly rate by dividing $187 by 11 hours. That yields $11 per hour. Now multiple the $11/hour rate by 8 hours of work resulting in $88.
Answer:
(8,-4)
Step-by-step explanation:
The difference between A and M is 2.5x and -4y
so B would be 5.5+2.5 and 0-4
(8,-4)
Answer:
The answer is 1-5x+135y
Step-by-step explanation: multiply the numbers 3 and 45 which give you 135
