Answer:
5x+0.50y=20
Step-by-step explanation:
A linear equation is an easier way to find a standard equation because it makes it easy to find x and y. So the equation would have to have x and y in it and this problem is 5 and 50 cents and his parents gave him the total which is 20 dollars so the equation would be
5x+0.50y=20

Answer: The answer is (B) 2x + 3(3x – 5) = 51
.
Step-by-step explanation: We are given three options and we are to select which choice shows the result of substituting 3x – 5 into the second equation for y.
So, y = 3x - 5.
Since the standard form of a linear equation i two variables is ax + by = c, so the second equation as given in the options must be of the form 2x + 3y = 51.
If we substitute y = 3x - 5, then this equation becomes
2x + 3(3x - 5) = 51.
Thus, (B) 2x + 3(3x – 5) = 51 is the correct option.
