Answer:
1665
Step-by-step explanation:
This is AP, where:
- First term is: 12= 3*4
- Last term is: 99= 3*33
- Common difference is: 3
- Number of terms is: 33- 3= 30 (because the 4th term is included)
The sum of all two - digit natural numbers which are divisible by 3 is 1665
Answer:
(4, - 2 )
Step-by-step explanation:
Given the 2 equations
x + y = 2 → (1)
x - y = 6 → (2)
Adding the 2 equations term by term will eliminate the term in y, that is
(x + x) + (y - y) = (2 + 6)
2x = 8 ( divide both sides by 2 )
x = 4
Substitute x = 4 in either of the 2 equations and solve for y
Substituting in (1)
4 + y = 2 ( subtract 4 from both sides )
y = - 2
Solution is (4, - 2 )
