Answer:
Step-by-step explanation:
The easiest way to understand the answer is to consider two straight lines.
y = 3x + 6
and 2y = 6x + 12
When you graph these two lines, one will be on top of the other. That will give you an infinite number of solutions.
The answer does not depend on the two equations being straight lines. All that is required is that one graph sits on the other. So you could have a pair of quadratics
y = x^2 + 3x + 10
2y = 2x^2 + 6x + 20
would also give you an infinite number of solutions.

The sum of the internal angles of an octagon is 1080°.
(There are four 
and 4 
, they sum to 1080°)

Answer: 2 1/2 miles
Step-by-step explanation:
To subtract fractions with different denominators (in this problem they are 10 and 5), you have to find the least common denominator or LCD (10). Then you have to multiply the numerator and the denominator of 4/5 by 2 to turn the denominator into the LCD (10).
1. So 2 4/5 turns into 2 8/10
2. Then subtract 2 8/10 from 5 3/10 to get the answer 2 1/2
4x+15y=G insert total hours- 30.5 for x and 1 for y and G will be your answer to problem B
