X-y=2 (*-2) --> -2x+2y=-4
2x+3y=14
------------------
2x+3y=14
-2x+2y=-4
------------------
5y=10
y=2
It will take 6 years for that to happen.
You can find this by setting Nichole's age as x and Sophie's age as x + 28 since she will always be 28 years older.
Now we are looking for a time that Sophie's age is equal to 2 less than 6 times Nichole's age. So we can set up the below equation.
6(x) - 2 = x + 28
6x - 2 = x + 28
5x - 2 = 28
5x = 30
x = 6
This let's us know that it needs to be when Nichole is 6, which is 6 years in the future.
Look ar the picture.
Your answer: 2 lines of symmetry.
Yes. since half of 50 is 25 it is correct to say that 18 is less than half
The wardrobe is 3x2 inches and the tree is 18 feet
