Answer:

Hi,

a=b+3

Step-by-step explanation:

$\begin{array}{c||c|c|c|c}&x^3&x^2&x&1\\---&---&---&---&---\\&1&-a&b&c\\x=-1&&-1&a+1&-a-b-1\\---&---&---&---&---\\&1&-a-1&a+b+1&c-a-b-1\\\end{array}$

$\begin{array}{c||c|c|c|c}&x^3&x^2&x&1\\---&---&---&---&---\\&1&-a&b&c\\x=2&&2&4-2a&2b+8-4a\\---&---&---&---&---\\&1&2-a&b+4-2a&c+2b+8-4a\\\end{array}$

Thus:

c+2b+8-4a=c-a-b-1

3b-3a=-9

a=b+3

Vickie made a recipe for 144 fluid ounces of scented candle wax. How many 1 cup candle molds can she fill with the recipe?

jeka57 [31]

There are 8 fluid ounces in 1 cup. You can solve this problem using these proportions:

$\frac{8}{1} = \frac{144}{x}$

It states that there are 8 fluid ounces in every 1 cup and 144 fluid ounces in every x cups. We have to solve for x using cross-multiplication:

$8x = 144 \\ x=18$

Vickie can fill 18 1 cup candle molds with 144 fluid ounces of scented candle wax.
