The maximum length is 5 . The 3 tall takes away from the 8 and then your left with 5.
Answer:
y = -2
x = 5
Step-by-step explanation:
3x - y = 17
-x + y = -7
here we can find the sum of the two equations
2x = 10
x = 5
now we can just plug in the value of x to find y
-(5) + y = -7
y = -2
Answer:
x =2
Option D is correct !!!
Step-by-step explanation:
By Pythagoras theorem we can solve this
we know that:
Well there is to equations here that must be equal. X+20=4X Four times old means 4X+X=5X.
If you work to simply the problem you get something that looks like this:
X+20=5X
20=4X
x=20/4 or 5 y/o!
19/6y+17=-21
19/6y=-38
y=-12
