Answer:
Step-by-step explanation:
Euler's formula is
V - E + F = 2
Givens
V = 15
E = 15
F = ?
Solution
15 - 15 + F = 2
F = 2
I'm not sure this makes sense, but it is what the formula gives you.
Given :7872 ÷ 305.
Because it's estimation. So, we need to estimate the number 7872 to 8000.
In order to divide 8000 by a number we need to estimate 305 to the 400. Because 400 is exact divisor of 8000.
If we divide 8000 by 400 we get 20.
And it's obviously less then 60000 ÷ 300= = 200.
20 < 200.
<h3>Therefore, Harrison is absolutely correct.</h3>
Answer:
y= -1/7x+23/7
Step-by-step explanation:
Draw out a horizontal line. Place 0 at the center. Then place evenly spaced tick marks on either side of 0. Label the right side of tick marks as 1, 2, 3, ... moving from 0 and going to the right
Label the left side of tick marks -1, -2, -3, ... starting at 0 and moving left
The location -3 on the number line is exactly 3 units away from 0. We start at 0 and move to -3 by moving 3 spots to the left; or we start at -3 and move 3 units to the right to get to 0.
Therefore, the absolute value of -3 is 3
Absolute value on a number line is the distance a number is from 0
The distance is never negative
