Answer:
x 2 y -4
Step-by-step explanation:
13x = -54 -20y give it is A
-10x = 60 + 20y give it is B
A + B the sum of the left side of equation is equal to the sum of the right side of equation
13 + (-10x) = -54 -20y + 60 + 20y
3x = 60-54
3x = 6
x=2
so put the x value in A or B equation you can receive y value (B is easier)
y = -4
The best way to answer this item is to use the Substitution method. Substitute the value of y from the first equation to the y of the second equation such that the second equation becomes,
-4x + 3(x - 4) = -3
Simplifying the equation,
-x = 9
Dividing both sides by -1 gives an answer of,
<em>x = -9</em>
Then, substitute the value of x in the first equation.
y = -9 - 4
<em> y = -13</em>
The answer to this item is letter B.

Answer:
C. 6 because any answer besides that is too low or too high.
Step-by-step explanation:
110.25 pitches so far- 150 at max. 5.75 pitches per game.
4: 4x5.75 = 23
110.25 + 23 = 133.25
5. 5x5.75 = 28.75
110.25 + 28.75 = 139
6: 6x5.75 = 34.5
110.25 + 34.5 = 144.75
7: 7x5.75 = 40.25
110.25 + 40.25 = 150.50 > which rounds up to 151
