A 4 digit addends could have a 5 digit sum because of the rule of regrouping.
Regrouping is a situation where carrying and borrowing is involves. So let’s have an example
8999
<span>+5678
</span>14677
so in this example, we added 8999 to 5678.
9+8 = 17, so we bring down 7 and carry 1
9 + 7 = 16 + 1 = 17 , so again we bring down 7 carry 1
9 + 6 = 15 + 1 = 16, bring down 6 carry 1
8+5 = 13 + 1 =14, since this is our last number, bring down 14..
=> 14, 677
So you see where x=-1 is
it is at (-1,-1)
answer is -1
35+55+a=180
90+x=180
-90. -90
A= 90
Answer:
x = 6
Step-by-step explanation:
Every side of an isosceles triangle will always be the same
What is the slope of the line that passes through the points (1, 3) and (5, –2)?
C.-5/4
slope = (-2 -3)/(5 -1) = -5/4
2.The sum of two consecutive odd integers is 80. What is the smaller number?
C.39
odd : 39 +41 = 80
39 is the smaller odd number
