Answer:
Here the given subtraction problem,
55 - 23
For finding the answer with help of the number line we will follow the following steps,
Step 1 : First find the number 55 on the number line.
Step 2: Count the position of 55 from 0 of the number line,
Step 3: Now count back from 55 to 23,
We will get 32.
Thus, 55 - 23 = 32.
If you look at the graph you can tell the graph is increasing before x = -2.
From x = -2 to x = 0, it's decreasing.
Then it's increasing again from x = 0 to x = 2, then decreasing after x = 2
So answer is the last one
It is increasing before x = -2 and from x = 0 to x = 2
In the middle:
x-coordinate= {7-(-1)}/2= 4
y-coordinate= (8-2)/2= 3
So centre is (4,3)
Answer:
147,590
Step-by-step explanation:
b/c the 90's are in the tens and 5 or more add one more, so since it's less than five, you round down. So the answer would be 147,590
Answer:
-2 =m
Step-by-step explanation:
–15 = 4m – 7
Add 7 to each side
–15+7 = 4m – 7+7
-8 = 4m
Divide each side by 4
-8/4 = 4m/4
-2 =m
