If you are setting it up as a proportion then you would muiltiply the 12 and x to get 12x. Then muiltiply the 80 and 1 to get 80. So 12x=80. Divide the 12 to get your final answer
Multiply the car by 2: 300 meters x 2 = 600 meters
30 seconds x 2 = 60 seconds.
The car also traveled 600 meters in 60 seconds, so the speed of the vehicles are the same.
No vehicle was faster.
Answer:
First answer is 1200
Second answer is 900 for each new employee
Step-by-step explanation:
First answer:
2200+1300+800+940+560+x = 7000
5800+x = 7000 subtract 5800 from both sides and you get your answer
x = 1200
Second answer:
x = 900. Each of the two employees made 900 a month or 1800 a month for both of them.
To find the average we take the total salaries and divide by the number of people to find the average salary. In this case, we know the average and we know all of the salaries, but two. We can figure this out.
(7000 + 2x)/8 = 1100 multiple both sides by 8 to clear the fraction/
7000 +2x = 8800 Subtract both sides by 7000
2x = 1800 Divide both sides by 2
x = 900
