Answer:
A) 44.25 hours
Explanation:
To round time to the nearest quarter-hour, round those times within 7 minutes of a 15-minute mark to that 15 minutes.
Thus, the time in and time out are rounded to the nearest quarter-hour in the table below:
Next, add the differences:
She worked a total of 44.25 hours.
Option A is correct.
Good morning Sonny
y-4x=7
2y+4x=2
We need to solve -4x+y=7 for y
Now let's start by adding 4x to both sides
-4x+y+4x=7+4x
y=4x+7
Now substitute 4x+7 for y in 4x+2y=2 so we can find the value for x
4x+2y=2
4x+2(4x+7)=2
12x+14=2
Add -14 to both sides
12x=14-14=2-14
12x=-12
Now divide 12 to both sides so we can find x
12x/12=-12/12
x=-1
Now we need to find the value for y by substitute -1 for x in y=4x+7
y=4x+7
y=(4)(-1)+7
y=3
Work done ;)
Answer : x=-1 and y=3
(-1,3)

Given that C = 15 n cm,
Substituting the value,
Solving above equation for r, divide both side by
Simplifying,
Formula for area of circle is given as,
Substituting the value of r,
Squaring the parenthesis,
Cancelling out the common term,
Therefore, area of circle in terms of n is
Answer:
2x + 1 = 11.
2x + 1 - 1 = 11 - 1 (subtracting both sides by the same number)
2x = 10.
2x/2 = 10/2 (dividing both sides of the equation by the same number)
x = 5.
