For which value or values are the expressions 15k+9 and 3(2k+3)+9k

Answers

Answer 1

Answer: remember you can do anthing to an equaiton as long as you do it to both sides

I think you are missing a relation symbol at the end
it could be an equals though (just my guess)

For which value or values are the expressions 15k+9 and 3(2k+3)+9k equal

15k+9=3(2k+3)+9k
use distributive prpoerty which says
a(b+c)=ab+ac so
3(2k+3)=6k+9

now we have
15k+9=6k+9+9k
add like terms
15k+9=15k+9
subtract 9
15k=15k
divide 15
k=k
since this is a true statement, any number will work for k

k=all real numbers

Roger gets $40 per day as wages and $4.50 as commission for every pair of shoes he sells in a day. His daily earnings goal is $112. Write an equation to determine how many pairs of shoes, p, Roger must sell in a day to meet his daily earnings goal.

Answers

112 = 4.5p + 40
subtract 40 from both sides
72 = 4.5p
divide by 4.5 on both sides to get 'p' by itself
16 = p
this means that Roger must make 16 pairs of shoes in order to meet his daily earnings goal of $112

Answer:

112=4.5p+40

A hardcover book sells for $24 at the bookmart. Ben pays a total of $25.02 for the book. What is the sales tax rate?

Answers

Increase in price = $25.02 - $24.00

= $1.02

Tax rate = $(1.02)/(24.00)$

Tax rate = 0.0425

0.0425 = 4.25%

What is 1/3 added to 5/6

Answers

7/6
Change 1/3 to 2/6 in order to have a common denominator.
Then add the numerators (2 and 5) and keep the denominator.

The first thing to do is to make the denominators. Since 3 goes into 6, the first fraction should simply be doubled:
1/3 + 5/6 = 2/6 + 5/6
5 + 2 = 7
7/6

1/3 + 5/6 = 1 1/6 or 7/6
