You do 9x27=243 then take 2x31=62 add 243+62=305 then take 305 and subtract it from 28 305-28=277
so if i did it right you should get n=277

Answer:
Independent Variable: Number of hours
Dependent Variable: Cost
Equation: C = 2x + 6
Step-by-step explanation:
The independent variable (x) is the variable that is manipulated. In this instance, that would be the number of hours a person rents out the bike.
The dependent variable (C) is the variable that is manipulated depending on the value of the independent variable. In this instance, that would be the total cost for renting the bike.
The total equation would be C = 2x + 6. The coefficient, 2, represents the charge of $2 per hour and the 6 represents the starting charge of $6.
Answer:
BADC
Step-by-step explanation:
-4x + 7 27 Subtract 7
-4x 20 Divide both sides by -4
x -5 B
3x - 10 < -25 Add 10
3x < -15 Divide by 3
x < -5 A
5(x - 2) > -15 Use distributive property
5x - 10 > -15 Add 10
5x > -5 Divide by 5
x > -1 D
x - 9 < -10 Add 9
x < -1 C
