If B is the midpoint of AC, that means that the distances from A to B and B to C are the same. The distance from A to B is 8x + 4, and the distance from B to C is 10x - 6, so we can set these two equivalent:
8x + 4 = 10x - 6
Solving for x:
4 = 2x - 6 (subtract 8x from both sides)
10 = 2x (add 6 to both sides)
5 = x (divide both sides by 2)
So, x = 5, which is the second option given.
Answer: 15 dimes and 13 nickels
Step-by-step explanation:
180 - 149 = 31
x/100 *149 = 31
1.49x = 31
x= 31/1.46 = 20.81 %
X=3, y=4
x=-2, y=9
Set x equal to anything, then isolate y to get the other number.
