Need some help, Thank you!!! ^^

stira [4]

Given:

$3b+8\geq 14$

To find:

The steps to solving the given inequality.

Solution:

We have,

$3b+8\geq 14$

Subtract 8 from both sides.

$3b+8-8\geq 14-8$

$3b\geq 6$

Divide both sides by 3.

$\dfrac{3b}{3}\geq \dfrac{6}{3}$

$b\geq 2$

Two steps are:

1. Subtract 8 from both sides of the inequality.

2. Divide both sides of the inequality by 3.

Therefore, the correct option is A.

Alex buys 5 DVDs. Each DVD costs $9. If Alex receives a $2 discount on each DVD, what is the total amount of money alex apends?

LekaFEV [45]

Answer:

The total amount of money Alex spends on 5 DVD = $ 35.

Step-by-step explanation:

Total number of DVD purchased by Alex = 5

The cost of each DVD = $9

So, the total cost of purchasing 5 DVD = 5 x ( csot of 1 DVD)

= 5 x ( $ 9) = $ 45

Now , the discount if 1 DVD = $ 2

So, the total discount of 5 DVD = 5 x ( Discount on1 DVD)

= 5 x ($ 2) = $ 10

⇒ The total amount Alex spends

= Total cost of 5 DVD - Discount on 5 DVD

= $ 45 - $ 10 = $ 35

Hence, the total amount of money Alex spends on 5 DVD = $ 35.
