Look at the picture.

The equation:

10x - 15 = 6x + 9 <em>add 15 to both sides</em>

10x = 6x + 24 <em>subtract 6x from both sides</em>

4x = 24 <em>divide both sides by 4</em>

Answer:

x=6

Step-by-step explanation:

If ABCD is a parallelogram, then AB = CD

AB=CD

10x-15 = 6x+9

Subtract 6x from each side

10x-6x -15 = 6x-6x+9

4x-15 = 9

Add 15 to each side

4x-15+15 = 9+15

4x = 24

Divide by 4 on each side

4x/4 =24/4

x=6

Please help if you can i really need it

Mila [183]

Answer:

Step-by-step explanation:

60 requests are made.

Spencer gets 25% of these requests. Convert this to a decmal (divide by 100) to get 0.25. 25% of 60 is:

$(0.25)(60)=15\\$

So Spencer gets 15 requests. Now do the same process for Tanvi:

$(0.10)(60)=6$

So Tanvi gets 6 requests. To find out how many more requests Spencer gets compared to Tanvi:

$15-6=9$

Therefore, Spencer gets 9 more requests than Tanvi.
