Answer:
80.
Step-by-step explanation:
Three digit number can only have three patterns
A. All digits are distinct
B. Two digits are same and third is different
C. All three digits are alike.
We need to calculate B
that is B= Total- A-C
Total numbers from 700 to 999= 299.
Number numbers having all digits distinct = 3×9×8= 216 ( first digit can have only three digits 7,8,9)
All three are alike = 3 ( 777,888,999).
So, 299 -216-3= 80.
Answer: -15
Step-by-step explanation:
Let the unknown number be 'x'
Using the statement we can form the equation:
4 + x = -11
Now, solve the above equation to get :
4 + x = -11
x = -11 -4
x = -15
The number is -15. To check our answer, substitute for x :
4 + (-15) = -11
4 - 15 = -11
The above equation is correct. Therefore, the number is -15.
