100-37=63
it helps to write the problem like this
100
- 37
since there are no units you need to borrow from the tens, but there are no tens so you need to borrow from the hundreds
now the equation could be written in two pieces like this
90 10
- 30 - 7
90-30=60
10-7=3
60+3=63
Answer: y=-14.5 hope it helps :)
Answer:
k = -10/7 and k = -3
Step-by-step explanation:
Given: <em>y</em> = <em>kx</em> + 2
where k is the slope of line and 2 is y-intercept.
∵ line <em>y</em> = <em>kx </em>+ 2 is passing through point <em>P</em> (-7, 12), ∴ <em>x</em> = -7 and <em>y </em>= 12
Now substituting the value of x and y in above equation,
<em>y </em>= <em>kx</em> + 2
12 =<em> k</em>(-7) + 2
-7<em>k</em> = 12 - 2
- 7<em>k</em> = 10
![k = \frac{-10}{7}](https://tex.z-dn.net/?f=k%20%3D%20%5Cfrac%7B-10%7D%7B7%7D)
In the same way, ∵ line <em>y</em> = <em>kx </em>+ 2 is passing through point <em>P</em> (3, -7), ∴ <em>x</em> = 3 and <em>y </em>= -7
<em>y </em>= <em>kx</em> + 2
Now substituting the value of x and y in above equation,
-7 =<em> k</em>(3) + 2
<em>3k</em> = -7 - 2
<em>3k</em> = - 9
<em>k</em> = -3
The first two steps would be A
From the given condition above, travelling from the northernmost part to the southernmost part would mean that the cars traveled half of the circumference of the circle. With the given value for the circumference of the circular track, the car traveled 1.35 km.
