<span>14-3y=4y
Add 3y to both sides so that the variable y is only on one side.
14=7y
Divide 7 on both sides so that the only thing remaining on the right side is the variable y.
Final Answer: 2=y</span>
4/8 is equal to 1/2. While this is true of one coin toss, it is not a 50% chance if you toss the coin twice. In tossing the coin twice you have the options of: heads, tails, heads, tails (One head and one tail per coin). Since there are four options, it is a 25% chance you will get heads twice in a row. 25% equals 1/4 which equals 2/8.
Two lines are perpendicular if and only if the two lines intersect at right angles. If a point is in fourth quadrant,then it coordinates at negative. If thecoordinates are negative, then thepoint is in the fourth quadrant. If a figure is a triangle, then it has three sides.
Amy: x skirts
Betty: 2x skirts
Carol: (2x) + 7 skirts
If Amy has 18 less than Carol, than Carol's equation minus 18 equals Amy's equation:
[(2x) + 7] - 18 = x
+18 +18
(2x) + 7 = x + 18
- 7 -7
2x = x + 11
-x -x
x = 11
Input the solution for x into the girls equation to double check.
Amy: 11
Betty: 2(x)
2(11)
=22
Carol: (2x) + 7
22 + 7
=29
Does Amy have 18 less than Carol?
Carol - Amy = 18
29 - 11 = 18
18 = 18
