Y=2x2−8x+5 is standard form
You need an equation system.
First, translate the text into equations :
y = total price for the bike
x = number of months
first bike :
y = 25x + 500
second bike :
y = 50x + 200
Then you have to solve the system by placing the two equations side by side and comparing them.
25x + 500 = 50x + 200
Solve to find the value of x
Answer:
x = 9
Step-by-step explanation:
First equation = 4x - 8
Second equation = 7x - 35
Seperate the equation with an equal sign to make it an equality equation and solve for X so :
4x - 8 = 7x - 35 (Given)
-3x - 8 = -35 (Subtraction property of equality)
-3x = -27 (Addition property of equality)
x = 9 (Division property of equality)
Solution:
x = 9
Answer: 75 degrees
Step-by-step explanation:
75+75+30=180
Answer:
222 2/9 hours
Step-by-step explanation:
Income = hours * dollars per hours
We need an income of 2000
We get $9/ hour
Substitute in what we know
2000 = hour * $9
Divide by 9 on each side
2000/9 = hours
222.222(repeating) = hours
222 2/9 hours
If we want to know how many days, we will divide by 5 since she works 5 hours a day
222 2/9 ÷5
44 4/9 days
