To solve this problem, let's set up a system of equations. To do this, we can let one of the two unknown numbers be represented by the variable x and the other unknown number be represented by the variable y. We know that the difference between the two variables is 7 and the sum of the two variables is 59, which allows us to create the two equations below:
x - y = 7
x + y = 59
To solve this system of equations, we are going to use linear combination, which means simply adding the two left sides of the equations together and adding the two right sides of the equations together. Because the first equation has a -y term on the left side and the second equation has a +y term on the left side, these are going to cancel out, leaving us with:
2x = 66
To solve this equation, we must get the variable x alone on the left side of the equation by dividing both sides of the equation by 33, giving us:
x = 33
To solve for the other number, we must plug this known value for x into one of our original equations, as follows:
x + y = 59
33 + y = 59
To solve for the variable y, we must subtract 33 from both sides of the equation to get the variable y alone. This operation gives us:
y = 26
Therefore, the two numbers are 33 and 26.

First convert it into minutes by multiplying 60,
3/4 * 60
Now, again with 60, in order to convert it into seconds,
3/4 * 60 * 60
3/4 * 3600
3 * 900
2700
In short, Your Answer would be 2700 seconds
Hope this helps!
Answer:
14ft
Step-by-step explanation:
12 yard pipe equals 36ft. Divided equally 3 times gives 3 pipes at 12ft per pipe. 2 of those are divided in half, making 4 6ft pipes. 1 of the 6ft pipes is cut into 3 2ft pipes. you now have 3 pipes at 2ft, 3 pipes at 6ft and 1 pipe at 12ft. the longest 2 pieces are 12ft and 6ft making 18ft. 2 shoetest pieces equal 4ft. 18ft minus 4ft equals 14ft.
1 h 3 min+1h 18 min+55 min +68 min= 63 min+78 min +55 min+68 min=
=264 min
264min*1h/60min=4.4 h
correct answer is 3d one
