Answer:
8
Step-by-step explanation:
I dont really get the question so i thought it was 15 - 7??
1/6 < 1/4 so 1/6 would equal 2/12 and 1/4 would equal 3/12 so which means if you take one from each it would be 5/12 but if you took 2 from the first one it would only be 2/12 which is why you need to read correctly because THE REASON MARK IS CORRECT IS BECAUSE 5/12 IS GREATER THAN 2/12
Let x be the time it takes Elias and Niko to polish the silver working together. If Elias works alone, he could polish all the silver himself in 40 minutes. Then, in 1 minute, he will make 
of the total work. If the same analysis is applied Niko, in 1 minute, will make 
of the total work.
Working together Elias and Niko will need x minutes to make all the work. Then, in 1 minute, they will make 
of the total work. So, the fraction of the total work they make in 1 minute is given by this equation:
Answer:
100
Step-by-step explanation:
The function takes in an X value and produces a Y value.
The Y value equals 24 times the X value plus 4 more.
This means that:
Y = 24X + 4
When the X value equals 4, the Y value will be:
Y = 24(4) + 4
Y = 96 + 4
Y = 100
When the X value is 4, the Y value is 100.
