Answer:
The answer is 15 Shirts
Step-by-step explanation:
We want to know what x is going to equal that makes the equation the same.
First, I make the euations equal to each other by substituting the y -->
7x + 50 = 10x + 5
Then, I combine my similar terms --> 45 = 3x
After that, I divide by 3 to get x on its own --> 
--> 15 = x
This means that after 15 Shirts are sold, the costs for both companies are the same.
Answer:
The first one is proportional and the second one is not. Because for the first one you can see that if you divide the number of pens by the cost you'll get the same answer for every single one. But for the second one if you divide the number of minutes by words typed you get a different answer for each one. You can also see if it's proportional or not if you draw it on the graph and it's a straight line. If it is the relationship is proportional if it isn't it's not proportional. Hope that makes sense :)
First you will subtract right to left and then what ur left with is the sum.
