Answer:
Multiply the second equation by −2 to get −8x − 6y = −30.
Step-by-step explanation:
{2x + 6y = 12
{4x + 3y = 15
{2x + 6y = 12
{−8x − 6y = −30 >> New Equation
* Doing this will give you <em>additive</em><em> </em><em>inverses</em><em> </em>of −6y and 6y, which result in 0, so they are both ELIMINATED.
** [3, 1] is your solution.

Answer C
When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy. Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius
The answer is 14 bolts.
1 dozen bolts have 12 bolts.
7 dozen bolts have x bolts
___
1 : 12 = 7 : x
x = 7 * 12 : 1
x = 84 bolts
1 bin has 7-dozen bolts (84 bolts).
1/6 bin has x bolts
1 : 84 = 1/6 : x
x = 84 * 1/6 : 1
x = 84/6 = 14 bolts
