Answer:
Create a single variable linear equation that has no solution. Solve the equation algebraically to prove that it does not have a solution.
Create a single variable linear equation that has one solution. Solve the equation algebraically to prove that there is one distinct solution for the equation.
Create a single variable linear equation that has infinitely many solutions. Solve the equation algebraically to prove that there is an infinite number of solutions for the equation
Step-by-step explanation:
Using linear pairs,
By the exterior angle theorem,
Marked price = 200 + 40% of 200 = 200 * 0.4*200 = 200 + 80 = $280
price after 25% discount = 280 - 0.25*280
can you work that out?
Answer:
x=-20
Step-by-step explanation:
x+8−8=−12−8
x=−20
Answer:
x - 5 = x - 2 and
x - 5 = 2 - x.
Step-by-step explanation:
x - 5 may be positive or negative so we have:
x - 5 = x - 2
and
x - 5 = - (x - 2)
x - 5 = 2 - x.
