If the question gives you another variable, just switch it out with n
C because if you plug one into the other the answer comes out as x and that is how you know it is an inverse
900. You round up, because it is above 850. :-)
Answer:
B) 105.20
Step-by-step explanation:
491.60 + 157.68 - 68.44 = 581.20
20 and 45x
We look for a number that can go into both numbers.
5 into 20 is 4 and 5 into 45x is 9x.
5: 20 45x
4 9x
So no other number can go into 4 and 9x again.
So the GCF of 20 and 45x is 5.
Hope this explains it.
