Simplify the Expression.
8c^2 - 1.5d <span />
the answer is x is greater then -7
to find this add 4 to each side
then divide by -2.
since you divided both sides by a negative the symbol flips and you get x is greater then -7
1 cup = 8 fluid
So 144 fluid = 144/8 = 16 cups
So 16 cups candle moles she can fill with the recipe.
Ok so cos(x) = sin(90-x) so using that you can get sin(7x-15) = sin(90-(3x+5)) so 7x-15 = -3x+85. 10x = 100 and x = 10. Use that to find the 2 angles are 55 and 35
