So, firstly, in order for us to know how much is each baseball card pack, we divide 12 dollars by 4 and we get 3. Therefore, each baseball card pack costs $3. So for 21 dollars, he can purchase 7 baseball card packs. 21 divided by 3 is 7. Hope this answers your question. Have a great day!
Answer:
Since we're dealing with absolute value we'll have two answers.
a= c/x-b/x
a= -c/x-b/x
Step-by-step explanation:
Since we can't combine any values inside the absolute value signs we get rid of the absolute value signs.
Now we have: ax+b=c
since we're trying to get a by itself, we subtract the b to get ax= c-b
Now we divide the x and since we can't directly put it with a single value on the right side, we have to put it with both the c and b. Now we have a=c/x-b/x.
For the second answer, you first put a negative with the c. ax+b= -c
Now you solve exactly the same way you did above.
Hope this helps! :)

Step-by-step explanation:
If we are to find f(x) + g(x) that we means that we are to add the functions together by combining like terms, if any, and put it all together into one function. Adding them looks like this:
and combining like terms gives us
Answer:
If she sells 17 units, she earns $595
To earn $600, Mei must sell 18 units. Her revenue will be $630.
Step-by-step explanation:
If Mei sells 17 ceramic vases, each one for $35, she will earn $35*17= $595. The formula I used above is:
Revenue ($)= Price ($)*Units sold
If she needs to earn $600, we need to transform the equation:
Units sold =Revenue($)/Price ($)
Units sold= $600/$35
Units sold= 17,14
Since Mei can not sell 17,14 units, then she must sell 18 units . Her revenue if she sells 18 units will be $630.
