Answer:
8
Step-by-step explanation:
Set up a ratio problem:
25 hours/2 tests = 100 hours/x
25x = 200
x = 8
The lowest common multiple of 2 and 7 is 14, so 14 days will pass before he does both chores again.
Answer:
5029
Step-by-step explanation:
There is a common difference between consecutive terms, that is
d = - 201 - (- 215) = - 187 - (- 201) = - 173 - (- 187) = 14
This indicates the sequence is arithmetic with sum to n term
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = - 215 and d = 14 , then
= [ (2 × - 215) + (46 × 14) ]
= 23.5 (- 430 + 644)
= 23.5 × 214
= 5029
The simplified form would be -4×^2-13x+9
