Answer:
C. 150
Step-by-step explanation:
The given angle and angle x are supplementary. This means that when added together they add to 180. So, to solve you can set up an algebraic equation like 180=x+30. Then, subtract 30 from both sides to get 150=x.
(x + 4)(x - 4) = 9
x^2 - 16 = 9
x^2 = 9 + 16
x^2 = 25
x = sqrt 25
x = 5
Answer:
x = 12
Step-by-step explanation:
We will label the unknown interior angle of the triangle d.
14x - 19 + d = 180
14x + d = 199
d = 199 - 14x
199 - 14x + 3x + 9x + 7 - 2 = 180
199 - 2x +5 = 180
204 - 2x = 180
204 = 180 + 2x
2x = 24
x = 12
We have that
13%---------------------------- ><span>$726
100%-----------------------------X
X=100*726/13=</span>$5584.62
therefore
$5584.62=$1,632+$(<span>sweatshirts)
</span>$(sweatshirts)=$5584.62-$1,632=$3952.62
the answer is
the profit from sweatshirt sales was $3952.62
