First you would have use the distributive property to make this an easier problem.So take 3 times k (if the variable has no number just add a one) and 3 times -6 to get the problem of 3k-18=15. Now you would add 18 to -18 and get 0 and do it on the 15. 15+18=33,now you have 3k=33.now you divide 3/3 and get 1 and divide 33 by 3 to get 11.
Answer is k=11

Joel wants to buy a new tablet computer from a store having a 20% off sale on all tablets. The tablet he wants has an original c
earnstyle [38]

Answer:

<u>Joel will have to pay $ 159.60 for the tablet.</u>

Step-by-step explanation:

1. Information given to us to answer the question correctly:

Discount percentage of the tablets = 20%

Original cost of the tablet = $ 190

Sales tax = 5%

2. How much will Joel pay for the tablet? Show your work in your notebook. Remember to use $.

Let's find the discounted price and the sales tax for that price, this way:

Discounted price = Original price - Discount

Discounted price = 190 - (190 * 0.2)

Discounted price = 190 - 38 = 152

Sales tax of the discounted price = 152 * 0.05

Sales tax = 7.60

Joel will have to pay = Discounted price + Sales tax

Joel will have to pay = 152 + 7.60

<u>Joel will have to pay = $ 159.60</u>

Answer:

89.84375

Step-by-step explanation:

Given that on a finance exam, 15 accounting majors had an average grade of 90. On the same exam, 7 marketing majors averaged 85, and 10 finance majors averaged 93.

To find weighted mean.

Here weights can be considered as number of majors in each subject

Marks x     90        85       93\\Weights     15          7         10\\Product     1350    595     930\\

Weighted total = 1350+595+930 = 2875

Weighted mean = weighted total/total students

=\frac{2875}{32} =89.84375
