Answer:
6
Step-by-step explanation:
The total of all the angles must be 180, since there is a straight line. We already know the 40 degree angle and the 90 degree angle, meaning that the remaining angle must be equal to 180 - 90 - 40, which is 50 degrees. Therefore, 50 = 7k + 8. 7k = 50-8 = 42, and k = 6.
It's probably 6300. Adding the two numbers together gives you 6271, which can be rounded up to 6300.
8x-6x=280 if this is not the answer tell me what I hate to do
Answer:
X+10 I think
Step-by-step explanation:
It sounds like the expression would be
4n + n = the total number of nickles Casey and Megan have. 4n is the amount Megan has and n is the amount Casey has. So if you add them together you should get the combined total! :)
