Answer: 4) 7c ^2d - 7c + 4d - 10
Explanation:
First write equastion as seen:
5c^2d - 4c + 3d - 3 + 2c^d - 3c+ d - 7
Next add the c^2d’s together:
7c^2d - 4c + 3d - 3 + 3c + d - 7
Add the c’s together:
7c^2d - 7c + 3d - 3 + d - 7
Add the d’s:
7c^2d - 7c + 4d - 3 - 7
Lastly add the normal numbers:
7c^2d - 7c + 4d - 10
Thus, that is your answer!
Hope this helps! :)
You would need one because you arent yet to 20 so it takes one tenth for example;
1.7 or 7/10
Thats my guess tho man if it is more complicated than that, SORRRYYYY
This question might look tough, but if we break it down, it's super easy! I'll walk you through the steps.
Firstly, we need to figure out the total amount of money she deposited over the 10 months. To figure this out, all we have to do is multiply the $76.50 per month by the 10 months.
76.50 * 10 = 765
There we have it. She deposited a total of $765 over the course of the 10 months. On to the next step.
Second, we need to figure out the total amount of money she spent over the 10 months paying for singing lessons. To do that, all we have to do is multiply the $30.50 it took for each month by the 10 months.
30.50 * 10 = 305
There it is! She spent a total of $305 on singing lessons over the 10 months. On to the next step.
Now, we must subtract the cost of the singing lessons over 10 the months by the amount she deposited over the 10 months. Since she deposited a total of $765 and she spent $305 on singing lessons, here's the equation we're doing.
765 - 305 = 305
There we go! She had a total of $305 left after the 10 months. I'll leave the last step to you, I know you can do it!
