Answer:
2x-3 = -11
Step-by-step explanation:
|2x-3| = 11
by definition of absolute numbers,
2x-3 = 11 (given)
or
2x-3 = -11 (answer)
Im pretty sure it would be doubling the length of each side
Answer:
5x + 10y = 125
Step-by-step explanation:
Let :
Number of nickel = x
Number of dime = y
Nickel = 5 cent
Dime = 10 cent
Total value = $1.25
Total value should be converted to cent since both dime and nickel are both in cent
= $1.25 * 100 = 125 cents
Therefore,
5x + 10y = 125 cents
Putting both equations into standard form, we have the system
x -2y = 4
x -2y = -12
The lines these equations describe are
parallel.
6 + (-3) would be the same as just saying 6-3 which would be equal to positive 3
