Answer:
Part A. It will take him 7 months
Part B. The equation is 30 - 45x + 250
Step-by-step explanation:
Part A. the answer is 7 because in 6 months Matthew will have $225 and if you add 30 you get $255.
Part B. It's the answer because its the only one that makes sense. 250 = 450 + 30. Its 45 not 450. 250 = 30.2 + 45. It's 30 not 30.2 and 30 30 well 30 30 doesn't make sense either.

Answer:
The sum of all integers is 774.
Step-by-step explanation:
Since √11 = 3.3166, and 3.3166 is not an integer, so the first integer is 4.
From 1 to 39, there are 39 integers. But we started with 4, so we take out 3 numbers (1, 2, 3). Therefore, there are 39 - 3 = 36 numbers left.
The total number between 4 and 39 is 36 = n.
Sn = n/2 x (a1 + an)
S36 = 36/2 x (4 + 39) = 18 x 43 = 774
