Answer:

k=2

Step-by-step explanation:

7(k+8)=70

We move all terms to the left:

7(k+8)-(70)=0

We multiply parentheses

7k+56-70=0

We add all the numbers together, and all the variables

7k-14=0

We move all terms containing k to the left, all other terms to the right

7k=14

k=14/7

k=2

Answer:

Step-by-step explanation:

P(x) = $\frac{2}{3x-1}$

Q(x) = $\frac{6}{-3x+2}$

P(x) × Q(x) = $\frac{2}{3x-1}\times \frac{6}{-3x+2}$

= $\frac{2\times 6}{(3x-1)(-3x+2)}$

= $\frac{12}{(3x-1)(-3x+2)}$

P(x) ÷ Q(x) = $\frac{2}{(3x-1)}$ ÷ $\frac{6}{(-3x+2)}$

= $\frac{2}{(3x-1)}\times \frac{(-3x+2)}{6}$

= $\frac{(-3x+2)}{3(3x-1)}$

The value of each winning ticket is an arithmetic series in which T (n) = -5 + 15n or $5 (3n-1). The first winner is 5 (3x1 - 1) = $10. The second winner is 5 (3x2 - 1) = $25. The tenth ticket wins $5 (3x10 - 1) = $5 (29) = $145.
