Answer:
A) 6,3
Why?
The midpoint, which is somewhat self-explanatory thanks to its name, is a point in the center of a line.
To answer this question properly, you need to analyze the line and assess the situation.
How did it go from x = 2 to x = 10? Let's see, if we count by two's across the line, you'll notice it makes more sense. So now we know that every square goes up by two. x = 6 is the exact center of the line.
I hope this wasn't confusing, it's tough to explain it!
Answer:
47
Step-by-step explanation:
x=1/2*94 because it is a centeralangel
Answer:
Boat speed = 75 miles/ h
Current speed = 25 miles/ h
Step-by-step explanation:
Remember that:
Where
s is the speed
d is the distance
t is the time.
If we call s the speed of the boat and we call c the speed of the current, then we have to:
Boat speed downstream (Boat speed in the same direction as river speed):
Where:
Boat speed upstream (Boat speed in the opposite direction than the river speed):
Where:
Then we have the following system of equations:
(1)
(2)
Add equation (1) with equation (2) and solve for s:
Now substitute s in equation (2) and solve for c
Finally
Boat speed = 75 miles/ h
River speed = 25 miles/ h
There are 54 cups of juice from one bottle.
54/54 makes one bottle of juice.
However, you are trying to find out how much bottles are needed to fill one cup.
54 - 1 = 53
Place 53 over the total amount (54)
53/54 is the amount not used
subtract it from 54/54
54/54 - 53/54 = 1/54
1/54ths of a bottle is used to fill one cup
hope this helps
You can rewrite as a sequence of values (the outputs): 2,5 ,8 , 11, ....
for the input 5, we must to have the output 14 (look that the sequence above, is take +3 every time)
So, for the input n, we must have
Why?
Look that, for n = 1, we need to have 2, and for n=2 we need to have 5, that correspond to take +3 for the predecessor...
