Answer:

see explanation

Step-by-step explanation:

(1)

Given

$\frac{n}{5}$ = - 0.3

Since n is divided by 5 then use the inverse operation, multiplication.

Multiply both sides by 5 to clear the fraction

n = 5 × - 0.3 = - 1.5

(2)

Given

- 2n = 4 $\frac{1}{3}$ ← change to an improper fraction

- 2n = $\frac{13}{3}$

Since n is multiplied by - 2 then use the inverse operation, division.

Divide both sides by - 2

n = $\frac{13}{-6}$ = - $\frac{13}{6}$

AveGali [126]

Answer:

C) (x - 3)

E) (x - 10)

Step-by-step explanation:

x² - 13x + 30

x² - 10x - 3x + 30

x(x - 10) - 3(x - 10)

(x - 10)(x - 3)
