Answer:
I'm pretty sure the answer to number one is 12g.
Step-by-step explanation:
To combine like terms, you combine all of the same variables.
For example, if you have 5x+7y+5x, you would combine like terms to make 10x+7x.
So for your first problem, we know that the combined like term is 15g. We know that one of the numbers combined was 3g. With that knowledge, you can subtract 15g-3g and get 12g.
I hope this makes sense, and helps you answer your other questions!

Step-by-step explanation:
i hope this is right
Kieva made 8 cupcakes. 8 * 5 + 8 = 48 desserts.
In order to get this, you just have to try out different numbers of cupcakes and adjust based on whether it's too many desserts total, or not enough.
Another way to figure it out is to say that 1 cupcake + 5 cookies = 6 desserts. Then just divide 48 by 6 to get 8 which will then show you that Kieva made 8 cupcakes.
Multiply the average by the number of exams to find total points:
8 x 55 = 440
9 x 60 = 540
The score of the 9th exam is the difference between the two totals:
540 - 440 = 100
They scored a 100
8 223/285 I think that is the right answer if no i am sorry
