Answer:
B
Step-by-step explanation:
Using the Pascal's triangle
Pertaining to the 8th term the coefficients are;
1, 8, 28, 56, 70, 56,28, 8 and 1 in that order
Expanding this,
the coefficient of the term x^7y is 8
We see that both equations have 4y in them. Subtracting the second equation from the first equation, we get (3x -2x) + (4y-4y) = 2 - 8, x = -6
Plugging x = -6 into any equation, we see that our answer is 18 + 4y = 2, 4y = 2 - 18 = -16, y = -4.
Our answer is x = -6, y = -4
In the question it is given that Louie has 20 more than half as many baseball cards as Gerardo does.So,
Let us assume that the number of baseball cards Gerardo has = X
Number of baseball cards that Louie has = 20 + X/2
Also the total number of baseball cards Louie and Gerardo has together is 350.
Then,
X + X/2 + 20 = 350
X + X/2 = 350 - 20
X + X/2 = 330
3X/2 = 330
3X = 330 * 2
3X = 660
X = 660/3
= 220
Number of baseball cards Gerardo has = 220
Number of cards Louie has = 130.

Answer:
Step-by-step explanation:
The given expression is x- 
= 2
and we have to solve this for the value of x,
( x- ) = (2)
x² - 15 = 2x
x² - 2x - 15 = 0
x² - 5x + 3x - 15 = 0
x ( x-5 ) + 3(x - 5) = 0
( x+3 )( x-5 ) = 0
( x+3) = 0
x = -3
or ( x- 5 ) = 0
x = 5
Therefore, x = -3 and 5 will be the solution.
Option E is the answer.
