Opposite angles are equal

$\\ \rm\longmapsto m+357=4m+6$

$\\ \rm\longmapsto 357-6=4m-m$

$\\ \rm\longmapsto 3m=351$

$\\ \rm\longmapsto m=\dfrac{351}{3}$

$\\ \rm\longmapsto m=117$

Louie has 20 more than half as many baseball cards as Gerardo does. Together they have at least 350 cards.

MrRa [10]

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.
