Answer:
Plan A - 20x+40
Plan B - 30x
Step-by-step explanation:
x will determine the number of months.
For example, Plan A's equation
If I paid for one month, I should get $60.
20(1)+40 = 60
Now for three months, I should get $100. Because Plan A charges $20/month after a one time fee of $40 for the new phone.
20(3)+40 = 100
On the other hand, Plan B gives away a free phone, meaning no one-time fees. It only charges us $30/month. That's easy.
30(1) = $30
30(3) = $90

Answer:
Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.
Step-by-step explanation:
Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.
Answer:
The solution is (2,6)
Step-by-step explanation:
Let
x-----> the number of hours to change a fuel injection unit
y-----> the number of hours to change a transmission
we know that
5x+10y=70 -----> equation A
8x+8y=64 -----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (2,6)
see the attached figure
