harina [27]

Dan started with 69 cards

Step-by-step explanation:

Let x be the initial number of cards

Then

According to "Dan bought 7 new baseball trading cards to add to his collection"

$x+7$

The next day his dog ate half of his collection.

$\frac{1}{2}(x+7)$

There are now only 38 cards left.

$\frac{1}{2} (x+7) = 38$

Multiplying both sides by 2

$x+ 7 = 38*2\\x+7 = 76$

Subtracting 7 from both sides

$x+7-7 = 76-7\\x = 69$

Hence,

Dan started with 69 cards

Find what x is? 5×3>4+8+x a good help for your brain!

MaRussiya [10]

Answer:

x = 2.25 or any number greater

Step-by-step explanation:

5x3 > 4 + 8 + x

Make them equal to each other to get x

5x3 = 4 + 8 + x

(5x)(3) = 12 + x

- x - 3 - 3 - x

4x = 9

$\frac{4x}{4} = \frac{9}{4}$

x = 2.25

Once you get x plug it in to get the truth of the expression
