the circumference of a circle is defined as:</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>
c = pi*diameter</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>
if we have x segments of length y, then we can fit:</em></u></h2><h2><u><em>
</em></u></h2><h2><u><em>
c/y = z</em></u></h2><h2><u><em>

She sold 8 pepper plants.
From this problem I made the equation
7p+p=64
I knew that it needed to be 7 times however many pepper plants she sold, so I substituted p until it equaled 64.
7*8+8=64
56+8=64
64=64
So she sold 8 pepper plants and 56 tomato plants for a total of 64 plants.
X = necklaces, y = bracelets
at least twice as many bracelets as necklaces
y > = 2x <===
x > 0 <===
half hour for necklace, 1 hr for bracelet...fewer then 20 hrs
0.5x + y < 20 <==
(2y² + 7y + 11) - (8y² - 5y + 7) you can distribute the negative sign to the second expression and then combine the like terms
new expression: (2y² + 7y + 11) (-8y² + 5y - 7)
2y² and -8y² equals -6y²
7y and 5y equals 12y
11 and -7 equals 4
The answer is -6y² + 12y + 4
