a = - 15 and b = - 9

distribute the left side of the equation

- 15x² - 25x - 5b

for - 15x² - 25x - 5b and ax² - 25x + 45 to be equal then the coefficients of like terms must be equal, hence

- 15x² = ax² ⇒ a = - 15

- 5b = 45 ⇒ b = - 9

For every watch that Sarah sells, she earns $4. She gets an additional bonus of $50 for every 25 watches she sells. Last month,

kotegsom [21]

Answer:

Step-by-step explanation:

25 watches equals a $50 bonus + 25 * 4

25*4=100

100+50=150

150 can go into 506 three times with a remainder of 56.

since it fits three times that is 75 watches

now divided the remainder by 4 and add this to 75.

56/4=14

75+14=89

89 watches

1.8 - 0.2x = -1.6 Subtract 1.8 on both sides

1.8 - 1.8 - 0.2x = -1.6 - 1.8

-0.2x = -3.4 Divide -0.2 on both sides

$\frac{-0.2x}{-0.2}=\frac{-3.4}{-0.2}$
