Answer:
5/6
Step-by-step explanation:
To add fractions the denominator (or lowest number must be the same)
They are not in this case, so we need to make it that way.
3 can be turned into 6 by multiplying by two. BUT REMEMBER, whatever you do to the top, you do to the bottom and vise versa.


Answer:
-37.5 m
Step-by-step explanation:
If we assume that "one full day" is 24 hours, then 15 hours represents the fraction 15/24 of a day. Since the drilling rate was constant, and was presumed to start from a height of 0, the height after 15 hours is that fraction of the day's work:
... (15/24)×(-60 m) = -37.5 m
It depends on how b approaches 0
If b is positive and gets closer to zero, then we say b is approaching 0 from the right, or from the positive side. Let's say a = 1. The equation a/b turns into 1/b. Looking at a table of values, 1/b will steadily increase without bound as positive b values get closer to 0.
On the other side, if b is negative and gets closer to zero, then 1/b will be negative and those negative values will decrease without bound. So 1/b approaches negative infinity if we approach 0 on the left (or negative) side.
The graph of y = 1/x shows this. See the diagram below. Note the vertical asymptote at x = 0. The portion to the right of it has the curve go upward to positive infinity as x approaches 0. The curve to the left goes down to negative infinity as x approaches 0.
The correct answer is C because your rounding the numbers to the nearest tens place.
Pick any negative integer you want for x. Let's say we pick x = -10. Replace x with this value. So replace x with -10
x - y = -1
-10 - y = -1
Now isolate y. We do this in two steps. First we add 10 to both sides. Then we multiply both sides by -1
-10 - y = -1
-10 - y + 10 = -1+10
-y = 9
-1*(-y) = -1*(9)
y = -9
So one ordered pair is (x,y) = (-10,-9). There are infinitely many of these ordered pairs. Another ordered pair is (-11,-10) which is found following the same steps as shown above. The only thing that matter is that x-y is equal to -1. There are infinitely many ways to subtract two values to get -1.
