12x=4(x-5)
distributive property to get rid of parenthesis 12x=4x-20
subtract x from one side to get the variable on one side 8x=-20
divide 8 by -20
x=-2.5
<span><span>Let x = amt of water evaporated
.05(50) = .08(50-x)
2.5 = 4 - .08x
.08x = 4 - 2.5
.08x = 1.5
x =
x = 18.75 lb of water evaporated
Check; amt of salt remains the same, only the percentage is different, right?
.05(50) = .08(50-18.75)
.05(50) = .08(31.25)
2.5 = 2.5</span><span>

Y-y1= m(x-x1)
y-2= -2(x+6)
y-2= -2x-12
y= -2x-10
Unless there is supposed to be a zero at the end of that 1, then the answer is no
Answer:
x>17/9
Step-by-step explanation:
-3(x-2) < 1/3
-3x+6 < 1/3
-3x < 1/3-6
-3x < -17/3
x > 17/9
Answer: Option A
Take not that this is a square bulletin board thus area = Length Times Base. Notice how it says its a square as well? thus telling us that each side is of equal length
Squaring the value N would give us the value of the one side of the board
