Answer:

Step-by-step explanation:

The term is in an arithmetic progression.

That means there is 6 between each term and the next one.

Givens

a = -30

d = 6

last term an = 42

Formula

L = a + (n - 1)*d

Solution

42 = -30 + (n -1 )*6 Add 30 to both sides

42+30 = (n - 1) * 6 Combine the terms on the left.

72 = (n - 1)*6 Divide both sides by 6

72/6 = n - 1

12 = n - 1 Add 1 to both sides

12 + 1 = n

n = 13

1) In order to solve the equation n/6 = -11.9, you must multiply by 6.

2) $-9m = -45 \\ \\ m = \frac{-45}{-9} \\ \\ m = \frac{45}{9} \\ \\ m = 5 \\ \\ Answer: \fbox {m = 5}$

3) $-14 = \frac{u}{8} \\ \\ -14 \times 8 = u \\ \\ -112 = u \\ \\ u = -112 \\ \\ Answer: \fbox {u = -112}$

4) $-117 = -9h \\ \\ \frac{-117}{-9} = h \\ \\ \frac{117}{9} = h \\ \\ 13 = h \\ \\ h = 13 \\ \\ Answer: \fbox {h = 13}$

5) $\frac{q}{19} = 5 \\ \\ q = 5 \times 19 \\ \\ q = 95 \\ \\ Answer: \fbox {q = 95}$
