Answer:
1) (2, 3)
2) (2, -5).
Step-by-step explanation:
2x – y = 1
2x +2y = 10 Subtract to eliminate the 2x:
2x - 2x - y - 2y = 1 - 10
-3y = -9
y = 3.
Plug this into the first equation:
2x - 3 = 1
2x = 4
x = 2.
2)
5x – y =15
x + y = -3 Adding to eliminate y:
5x + x - y + y = 15 + -3
6x = 12
x = 2
Plug this into the first equation:
5(2) - y = 15
-y = 15 - 10 = 5
y = -5.

Answer:
0.00597
Step-by-step explanation:
Given,
Total number of cards = 52,
In which flush cards = 20,
Also, the number of spade flush cards = 5,
Since,
Thus, the probability of a hand containing a spade flush, if each player has 5 cards
= 0.00597
Answer:
18/25, 5/4, 1.3
Step-by-step explanation:
What you need to do is to divide each fraction so that you can change to a number.
18÷25=0.72
5÷4=1.25
5 degrees. Since its a right triangle, one of the angles is a right angle meaning it measures 90 degrees and 90+85=175 degrees and because of the Triangle Sum Theorem, we know a triangle equals 180 degrees. So 180-175= 5 degrees.
