Step-by-step explanation:
= - 4
= a* + (3- 1) d*
- 4 = a + 2d . . . . . . . . .(i)
= - 29
= a + ( 8 - 1) d
- 29 = a + 7d . . . . . . . . (ii)
subtracting equations (i) and (ii)
25 = 5d
d = -5
placing d = -5 in equation (i)
a - 10 = -4
a = 6
For an arithmetic Progtession
= a + (n - 1)d
= 6 + (n- 1)-5
= 6 - 5n + 5

If you mean fraction,
Tom: 2/3
Sam: 1/4
Now we change the denominator.
Tom: 6/12
Sam: 3/12
6/12 + 3/12 = 9/12
9/12 can be simplified, so 3/4 of the pie was eaten.
4/4 - 3/4 = 1/4
The answer is 1/4.
Answer:
2. 12
Step-by-step explanation:
The answer is a+b+c = d it’s is equivalent to a and d
