Answer:
Step-by-step explanation:
1) y = 50x + 2500
2) y = 200x + 1000
if we build a system with the two equations, we have:
50x+2500 = 200x + 1000
150x = 1500
x = 10
y = 2000 + 1000 = 3000
3) 10
4) $3000
Speed = 90km/hr
Time = 1min = 1/60 hr
Speed = Distance / Time
Distance = Speed * Time
D = (90 km/hr) * (1/60 hr)
D = 1.5 km (ANSWER)
Total area = area rectangle + area of the triangle
= 8 * 13 + 0.5* 6 * (14-8)
= 122 unit^2
Answer:
<h3>C. t = x + x - 6</h3>
Step-by-step explanation:
Let the time use by other one technician be x
if the other technician takes 6 minutes less than the first technician, then the time taken by the other technician will (x - 6)
The total amount of time t it would take to run the tests if the technicians work together will be expressed by taking the sum of the time taken by the two technician as shown.
First technician = x
Second technician = x-6
Sum of the time taken
t = x+ (x-6)
Hence option C is correct
