The sum of all the angles must be 180 degrees.
Given :
An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 g of an alloy containing 12% copper with 78 g of an alloy containing 92% copper.
To Find :
How many grams of copper are in the resulting mixture what percentage of the resulting mixture is copper.
Solution :
Mass of copper in 50 gm alloy = 
.
Mass of copper in 78 gm alloy = 
.
Total mass of copper, ( 6 + 76.44 ) gm = 82.44 gram.
Percentage of copper in resulting mixture :
Hence, this is the required solution.
Answer:
3x = - 6
Step-by-step explanation:
Three times a number is at most negative six
3 times a number would be 3 times x, is means the equal sign (=)
3x = - 6
<h3>What is Cost Price?</h3>
This refers to the price which a seller or a merchant purchased a good and this would be a good determinant to find out the selling price so that he could make a good profit.
<h3>Selling Price</h3>
This refers to the price which a good is sold and there are several factors which are taken into account such as:
Mathematically, the<em> profit= </em>Cost price - Selling Price (Expenditure)
Please note that your question is incomplete so I gave you a general overview so that you could have a better understanding of the concept.

Answer:
D
Step-by-step explanation:
you can just find the value of y and try some number of x
i.e. if x = 0, both of them will be 0
x = 1
G(x) result is -2
F(x) result is 1
x= -1
G(x) result will be 2
F(x) result is -1
so from these we can prove that G(x) is bigger graph than F(x) but flip vertically by y axis
