I believe you set them equal to each other.
2x+4=5x-9
x=4.3
2(4.3)+4=12.6
I think the answer is 12.6
Answer:
The Number is 8.
Step-by-step explanation:
Let the number be x.
Given:
1/2 is subtracted from four times the reciprocal of a number, the result is 0.
Hence the equation will become like;

Now Solving the equation we get.

Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.
Hence the number is 8.
Answer:
Step-by-step explanation:
5-0.5i
Answer:
1.90 hours
Step-by-step explanation:
We need to first find the unit rate, the number of minutes taken to fill 1 gallon.
It is given, 2.87 gallons per 1 minute, to get "how long" it will take to fill up 1 gallon, we have to divide the number of minutes (1) by the number of gallons (2.87).
So,
1/2.87 = 0.3484 minutes per gallon
Now, we need the time it will take to fill 328 gallons. We simply multiply 328 by the unit rate found (0.3484). We have:
328 * 0.3484 = 114.2857 minutes
We need the answer in hours, so we divide by 60:
114.2857/60 = 1.90 hours
