Look up the.name of the book online with anser sheet I had that same book just find the page
Answer:
744
Step-by-step explanation:
(x - 10) + (x - 11) + ( 3x + 6) = 180
5x -15 = 180
5x = 195
x = 39
y = 3x + 6
y = 3(39) + 6
y = 117 + 6
y = 123°
Answer:
This system of equations has no solution.
Step-by-step explanation:
Solving a system of equations can be done using a few different methods. Since your second equation is already solved for 'y', you can substitute this expression (-
x + 3) for the value of 'y' in the first equation:
2x + 4(-
x + 3) = 10
Distribute: 2x - 2x + 12 = 10
Combine like terms: 0 + 12 = 10 or 12 ≠ 10
Since the variables cancel out and 12 ≠ 10, there are no solutions to this system.
