Answer: 405 dollars
Step-by-step explanation:
200 * x = 270
x = 270 * 300/200. x =405 dollars
Check the attached answer.
Answer:
Step-by-step explanation:
1 3/5 + 2 5/10 = 26/10 +25/10 = 51/10
Using the process of elimination, we will be able to determine the answer. So, 5x+3y=-10 multiply it by *3 to change the equation into 15x+9y=-30. Then to change 3x+5y=-6 multiply it by *5, to change it into 15x+25y=-30. So now with these two equations 15x+9y=-30 and 15x+25y=-30, use subtraction to get rid of the variable x.
Thus,
15x+9y=-30
-
15x+25y=-30
which will leave you with
-16y=0
thus, y=0
Then, plug y back into the original equation to find x
5x+3(0)=-10
5x=-10
x=-2
Thus the point of intersection is (-2,0)
-2 being the x, and y being 0.
