2x*2 + 6x + 80
First we have to use distribution property
2(x*2 + 3x + 40)=0
Divide 2 to both sides
X*2 + 3x + 40=0
Multiply -1
-x*2 -3x-40=0
Add two numbers to get 3x
Multiply same two numbers that you add to get 40x*2
Add
-8x+5x= -3x
Multiply
-8x . 5x= -40x*2
-x*2-8x+5x-40
(X*2-8x) + (5x-40)
X(x-8)+ 5(X-8)
Common factor
(X-8)(x+5)
This would help you!
3/(x+2) = 2/x
multiply both fractions by x(x+2) to cancel out the bottoms
so it becomes 3x = 2x+4
ow subtract 2X from both sides and you get
x = 4
so it took Juan 4 hours
it took Yumi 2 hours more so 4+2 = 6 hours
16/21 is the correct answer
7/8
3/4
I'm order for them to have the same denominator you need to multiply so:
¾×2=6/8
So she drank 6/8 pints of water
