Simple the fraction into the population of the x and times it by Z
Answer:
380 = 40h +200 (equation)
4 1/2 hours (solution)
Step-by-step explanation:
The total cost is the sum of labor cost and parts cost. The labor cost depends on the number of hours.
__
An equation describing Terry's charges might be ...
total = labor cost + parts cost
380 = 40h +200 . . . . . . labor was $40 per hour for each of h hours
180 = 40h . . . . . . subtract 200
4.5 = h . . . . . . divide by 40
Terry was charged for 4 1/2 hours of labor.
Answer:
The rate is 6 for all of them
Step-by-step explanation:
The rate would be the price for one taco, so you divide the cost by the number of tacos you're getting.
Since triangle STU and TVW are similar angle VWT and SUW are equal, this means:
106-5x=7x-14
(106)+(14)=(7x)+(5x)
120=(12x)
10=(x)
Angle VWT=106-5x=106-(5)(10)=56
You can rewrite your function as
This implies that
Now, we have , so it counts as a solution.
On the other hand, depending on the coefficient a, b and c, the cubic equation
can have either one or three solutions.
So, we have the solution x=0, and then one or three solutions coming from the cubic part. The equation as a whole thus have either two or four solutions, depending on the coefficients.
