70x + 490=1050
-490 -490\
70x= 560
divide both sides by 70
x = 8
8 passengers
Answer: 2/3
Step-by-step explanation:
3/5 divided by 9/10 = 3/5 x 10/9
I got 30/45 which simplifies to 2/3
- 2x - 11 = - 25 :) hope this is ok
Answer:
Domain is all values of X or (-∞,∞)
Range is all the possible values of Y. Since it goes up to 3, and then it goes down, it's all values less than or equal to y, or (-∞,3] or y ≤ 3 (depending on how you need to enter the response.

Answer:
Step-by-step explanation:
Find the sum of the first 42 terms of the following series, to the nearest integer.
2,7,12
Solution
The sum is given by
SUM_n=n/2*(a_1+a_n)
a_n=a_1+(n-1)d
a_1=2, n=42, d=5
The 42nd term is therefore given by
a_42=2+(42-1)5=207
SUM_42=42/2*(2+207)=21*209=4389
The sum of the first 42 terms of the series, therefore, is 4389
