Answer:

The answer is option 2.

Step-by-step explanation:

The first step to solve for y, you have to subtract 7x on both sides in order to make y as a subject :

7x - 10y = 30

7x - 10y - 7x = 30 - 7x

- 10y = 10 - 7x

Vladimir79 [104]

Answer:

D) 15

Step-by-step explanation:

This is an arithmatic progression.

The formula for the sum of arithmatic progression is

s =  \frac{n}{2} (2a + (n - 1)d)

where d is the common difference between successive terms and a is the first term. By applying this formula,

120 =  \frac{n}{2} (2(1) + (n - 1)(1)) \\ 120 =  \frac{n}{2} (1 + n) \\ n(1 + n) = 240 \\ n {}^{2}  + n - 240 = 0 \\ (n - 15)(n + 16) = 0 \\ n = 15 \: or \: n =  - 16(reject)
