Set up an equation, where n is the original number. Since there is a 40% increase, 40% of itself is added to itself to make 14:
n + .4n = 14
You can now combine the n and .4n, since they're compatible terms. Keep in mind that n = 1n:
1.4n = 14
Divide each side by 1.4 to solve for n:
n = 10
The original number is 10.

Step-by-step explanation:
Given equation :
= 0
x= ±1
x= 1 and x= -1
±1 lies in solution set of real numbers !
The answer is B.
After writing the numerators above the common denominator, you get -10 + 9/15
Which is -19/15

The heat absorbed by the ice cube is calculated by the following formula:
![Q = (10\,g)\cdot[(2.090\,\frac{J}{kg\cdot ^{\textdegree}C} )\cdot (0^{\textdegree}C +12.2^{\textdegree}C)+334\,\frac{J}{g} + (4.186\,\frac{J}{kg\cdot ^{\textdegree}C})\cdot (30.2^{\textdegree}C-0^{\textdegree}C)]](https://tex.z-dn.net/?f=Q%20%3D%20%2810%5C%2Cg%29%5Ccdot%5B%282.090%5C%2C%5Cfrac%7BJ%7D%7Bkg%5Ccdot%20%5E%7B%5Ctextdegree%7DC%7D%20%29%5Ccdot%20%280%5E%7B%5Ctextdegree%7DC%20%2B12.2%5E%7B%5Ctextdegree%7DC%29%2B334%5C%2C%5Cfrac%7BJ%7D%7Bg%7D%20%2B%20%284.186%5C%2C%5Cfrac%7BJ%7D%7Bkg%5Ccdot%20%5E%7B%5Ctextdegree%7DC%7D%29%5Ccdot%20%2830.2%5E%7B%5Ctextdegree%7DC-0%5E%7B%5Ctextdegree%7DC%29%5D)
