Answer:
Step-by-step explanation:
312.50= a+0.25a
We need to combine like terms a=1. All variables without a value equal 1.
a+0.25a= 1.25a
312.50= 1.25a
Divide both sides by 1.25, since 1.25 is being multiplied by a.
a= 250
A, B, C
Got it right on khan academy
multiply each term in the bracket by the expression outside the bracket

idk whats cow but w over co
Answer:A) -4/3 B) 1/2 C) -5/4
Slope = (y2 - y1) / (x2 - x1)
For A) let (x1, y1) = (8, -7), (x2, y2) = (5, -3)
Slope = (-3 -(-7)) / (5 - 8) = 4/-3
For B) let (x1, y1) = (-5, 9), (x2, y2) = (5, 11)
Slope = (11 - 9) / (5 - (-5)) = 2/10 = 1/2
For C) let (x1, y1) = (-8, -4), (x2, y2) = (-4, -9)
Slope = (-9 -(-4)) / (-4 - (-8)) = -5/4
y = 10
x = 64
the equations containing y are adjacent angles in a parallelogram, meaning that they are supplementary, so we can create an equation:
5y + 2 + 12y + 8 = 180
solve this to get y = 10
the equation for x would be 2x + 5y + 8 = 180 because these angles are also supplementary
solve this to get x = 64
