Answer:
The number is 24
Step-by-step explanation:
This can be written algebraically as:
Solve for x, in which the steps are shown below.
Thanks for the question! :)
Let the cost of the dryer = x
let the cost of the washer = y
x + y = 750
y = 2x
Substitute:
x + 2x = 750
3x = 750
x = 250
250 + y = 750
y = 500
Therefore, the cost of the washer is $500 and the cost of the dryer is $250! :)
I hope this helps you! :D
So basically u would divide the top and bottom by 2 to get 15/12 then u would divide the top and bottom by 3 to get 5/4.<span />
Answer: 1144
Step-by-step explanation:
Given: Machine A makes 7 parts every 10 minutes.
i.e. it makes parts in 1 minute.
Machine B makes 16 parts every 15 minutes.
i.e. it makes parts in 1 minute.
On Monday,
machine A makes parts for 12 hours(720 minutes). [1 hour = 60 minutes, 12 hours = 12 x 6 = 720 minutes]
i.e. Total parts made =
i.e. Total parts made = 504
machine B makes parts for 10 hours(=60x 10=600 minutes)
i.e. Total parts made =
i.e. Total parts made = 640
Total parts made by both machines = 504+640 =1144
Hence, the total number of parts made by the two machines on Monday=1144.
