Answer:
14x
Step-by-step explanation:
You expand 2(7x+-3) (which seems to be 2(7x-3)):
6+14x-6
the sixes cancel out and you're left with
14x
Answer:
A
Step-by-step explanation:
Answer:
add like terms on both sides (3x+6=3x+21
subtract like terms (x+6=21)
subtract like terms (x=15)
There is a formula you can use:
Time = (Worker1 * Worker2) / (Worker1 + Worker2)
Time = (10 * 6) / (10 + 6)
Time = 60 / 16
Time = 3.75 hours
The equation is true.
y^13/y^12 = y^8 * y^-9
y=y^8 * y^-9
y=y^-1
y=1/y
y-1/y=0
y
y^2 - 1 = 0
y = 1 , -1
