Answer:

The number is 7

Step-by-step explanation:

Let x be the unknown number

difference is subtraction and is means equals

3 ( x-2) = 15

x-2 = 5

Add 2 to each side

x-2+2 = 5+2

Pls solve fast pls help

Svetlanka [38]

Answer:

The Answer should be 6%

Step-by-step explanation:

Given,

MP =1500 and Discount =10%

So, SP = 1500 × 90% =1350

We know, profit = $\frac{sp-cp}{cp}$ × 100%

=>20 = $\frac{1350-cp}{cp}$ × 100

=>CP = 1125

Now, if profit =12%

then, SP' = 1260 ;(using previous equation for profit and CP=1125)

So, SP' = MP × (100 -Discount )

∴ Discount = 16% ;(SP' = 1260 and MP = 1500)

So, Discount should be increased = 16% - 10% = 6%

Well, the angle looks like it is an obtuse angle, right? And we know that obtuse angles are greater than 90 degrees, so wouldn't the answer be A. 115 degree?
I think the answer is 115 degrees. Hope this helps!
