Answer:
discount $45
new price $135
Step-by-step explanation:
180 * .25 = 45
they get 45 dollars off
180 -45 = 135
sale price $135
The LCM is multiple which is useful if fractions need to be expressed in the same name, and the further discussion can be defined as follows:
When the other number is multiple, LCM will have the larger number:
Example:
Otherwise;

the greater number will be the lcm if the other number is a multiple
For instance:
the lcm of 2 and 4
the lcm is 4 as 2 and 4 are both multiples of 4
Y=3x-13
3x+2y=19
The solution to the system of equations is x = 5 and y = 2.
Given that:
The system of equations:
y = 3x - 13 (1)
3x + 2y = 19 (2)
Step 1: Solve equation (1) for Y:
y = 3x - 13
Step 2: Substitute y from equation (1) into equation (2):
3x + 2(3x - 13) = 19
Step 3: Simplify the equation and solve for x:
3x + 6x - 26 = 19
9x - 26 = 19
9x = 19 + 26
9x = 45
x = 45/9
x = 5
Step 4: Substitute x = 5 into equation (1) to find Y:
y = 3(5) - 13
y = 15 - 13
y = 2
So, the values of x and y are 5 and 2, respectively.

Answer:
none
Step-by-step explanation:
"they are the same" translates to ...
x = x +2
0 = 2 . . . . . . subtract x from both sides. — a FALSE statement
There are no values of x or y that make this true.
_____
The two equations describe parallel lines, so they cannot be "the same." There are no points of intersection.
