Kenny had 5/7 more trading cards than lee. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee.

svp [43]

Answer:

Step-by-step explanation:

Let X is the number of cards Kenny has

Let Y is the number of cards Lee has

1. Kenny had 5/7 more trading cards than lee, it means

X = Y + 5/7X (1)

2. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee, it means:

X + 50%X = Y + 220 (2)

So, we solve the 2 equations to find out X and Y

$\left \{ {{X=Y + 5/7X} \atop {1.5X=Y +220}} \right.$

<=> X = $\frac{3080}{17}$ and Y = $\frac{880}{17}$

<=> X ≈181 and Y ≈ 52

How to Find x value: 9-0.75(x+8)-5=-6.5

Dahasolnce [82]

Here's how to find the value of x:

<span>9 - 0.75 ( x + 8 ) - 5 = -6.5 find the difference of 9 - 0.75

</span><span>8.25 ( x + 8 ) - 5 = -6.5 add 5 to both sides
</span>
8.25 ( x + 8 ) = -1.5 distribute 8.25 to x and 8

8.25x + 66 = -1.5 subtract 66 from both sides

8.25x = -67.5 divide both sides by 8.25

x = 18.18181818...... the value of x is 18 2/11

hope this helps
