Regrouping in subtraction means that if you can't subtract because the digit on the bottom has a greater value than the digit on the top (such as 3-6)m so in this case you would have to regroup twice.
Answer:
37.5
Step-by-step explanation:
5*15=75 then 75/2=37.5
The midpoint is 1. Between A and B, there are a total of 14 marks on the number line. If you start at -6 and move up 7 marks, you will land on 1. The number 1 is in the middle of -6 and 8.
We know that
<span>a) the slope-intercept form of the line---------------> y=mx+b
b) </span><span>if two lines are parallel both have the same slope
</span>then
<span>passes through the point (1,0) and is parallel to x-y=7
Step 1
Find the slope
</span>x-y=7------------> y=x-7------------> m=1
Step 2
Find the slope-intercept form of the line---> y=mx+b
point (1,0) m=1
0=(1)*(1)+b------> b=-1
y=(1)*x-1--------> y=x-1
the answer is
y=x-1
