Answer to break even, cost = earnings= $455, number of miles to cover is 11
Step-by-step explanation: cost =422+3x, where x= number of miles covered
Earnings=400+5x
St break even, cost = earnings, then solving the linear equation, by collecting like terms, and dividing through by 22. x=11, the Pu x=11 in the either the cost or earnings expressing to get 455

Answer:
The answer to your question is x = 3.356 cm
Step-by-step explanation:
This is a right triangle so we can use the Trigonometric functions to solve this problem.
Data
Ф = 40°
Adjacent side = 4 cm
Opposite side = x
Process
1.- We must know the lenght of the opposite side so we must use the tangent to solve it.
tangent Ф = 
2.- Solve it for Opposite side
Opposite side = tanФ x Adjacent side
Opposite side = tan 40° x 4
Opposite side = 0.839 x 4
Opposite side = 3.356
Opposite side = x = 3.356 cm
Answer:
x=4
Step-by-step explanation:
3/2.(x-6)=-3
x-6 =-3:3/2
x-6 =-2
x =-2+6
x =4
