The first one has a negative. You shouldn't have a negative isolated variable,
-x = 5y -1, Multiply everything by -1,
x = -5y + 1,
For the second one, you isolate the x,
x + 2y = 13, subtract 2y from both sides,
x = 13 - 2y.<span />
<span>Suppose 4 members (m) of a family are splitting an 8 dollar bill. How much money will each member lose if they split the bill evenly?</span>
Answer:
m
OR
62.8318531 m
Step-by-step explanation:
This is actually pretty simple
The distance the tip travels is the arc length and the length of the pendulum is the radius of a circle
The formula for arc length is <u>Angle in Radians x Radius</u>
<u></u>
So pi/12 * 4 = pi/3 m
We know this is how much it travels every second so it is going at pi/3 m/s
One minute is 60 seconds
pi/3 * 60 = 20pi m
The right answer would be Arithmetic
4 cups of pecans = 5 cups of walnuts
x cups of pecans = 8 cups of walnuts
CROSS MULTIPLY
4*8 =5x
5x = 32
DIVIDE BOTH SIDES BY 5
5x/5 = 32/5
x=6.4
Therefore, 6.4 cups of pecans would be added to 8 cups of walnuts
