Answer:
5x - 2y = -2
Step-by-step explanation:
When subtracting one equation from the other, we are essentially just subtracting the left side of the second equation from the left side of the first equation and doing the same thing with the two right sides.
Here, we are subtracting (-7x + 3y) from (-2x + y):
(-2x + y) - (-7x + 3y)
Let's get rid of these parentheses. Remember that when we have a subtraction sign before a parentheses, we need to distribute a -1 to each term within those parentheses:
(-2x + y) - (-7x + 3y) = -2x + y + 7x - 3y = -2x + 7x + y - 3y = 5x - 2y
Now on the right side, we're subtracting 2 from 0:
0 - 2 = -2
Put it all together:
5x - 2y = -2
Hope this helps!
Assuming that the number cube is 6 sided
6 is one number in a 6 sided cube, so the probability is: 1/6
heads is one side of the coin, with two in all: 1/2
Multiply the two fractions together
1/6 x 1/2 = 1/12
1/12 is your probability
hope this helps
To answer, change the 6 into a fraction
6 x 6/6 = 36/6
36/6 + 4/6 = 40/6
Simplify
40/6 = 6 4/6, or 6 2/3 (simplified)
