He has 87 cards then he gets 9 more which is 96, he then gives 16 away which is 80, then he is given 3 which is 83 he sells all 83 cards to the collector & the collector gives him $124.50 each card is worth $1.50
8(2x - 14) + 13 = 4x - 27
Simplify the parentheses
16x-112+13= 4x-27
Simplify the non-x terms
16x-99=4x-27
Move the terms of x to one side
12x=72
Divide
x=6
Answer:
9 and -3
Step-by-step explanation:
Let the first number be x
Second number = y
x + y = 6
x = 15 - 2y
15 - 2y + y = 6
15 - y = 6
-y = 6 - 15
-y = -9 ( - sign gets cut cuz there is - sign at both the sides)
Therefore, first number = 9
x + y = 6
x = 9 = 6
x = -3
Therefore, second number = -3
Proof:
9 + (-3) = 6
Hope this helps

Answer:
The first answer is correct.
(x + 1)^2 + (y - 2)^2 = 1
A circle with the midpoint M(Mx, My) and the radius r can be written as
(x - Mx)^2 + (y - My)^2 = r^2
