1. Set up the long addition.
2 4 7
+3 5 8
_______
2. Calculate 7+8, which is 15.
since 15 is two-digit, we carry the first digit 1 to the next column.
1
2 4 7
+ 3 5 8
________
5
3. Calculate 4+5, which is 9. Now add the carry digit of 1, which is 10. Since 10 is two-digit, we carry the first digit 1 to the next column.
1 1
2 4 7
+ 3 5 8
________
0 5
4. Calculate 2+3, which is 5. Now add the carry digit of 1, which is 6.
1 1
2 4 7
+3 5 8
______
6 0 5
5. Therefore, 247 + 358 = 605.

Step-by-step explanation:
Answer:
x is an unknown quantity whose value is determined based on any algebraic equation it is used in.
Step-by-step explanation:
Step-by-step explanation: If you take a look at the right side of the equation, a 3 is being added to our variable <em>x</em>.
If you were going to solve this equation, you must subtract 3 from the right side and the left side to isolate our variable.
You would end up with 4 = x.
Answer:
Step-by-step explanation:
we are given
A student randomly guesses on 10 true/false questions
so,
there only true and false
so, probability getting true question is
so, probability getting false question is
the student gets 5 out of 10 questions right
so,
r=5
we can use binomial probability formula
now, we can plug values
we can simplify it
and we get
