Answer:

Step-by-step explanation:

149.99 * (2/3) = 99.99, so the coat will cost $99.99 now.
Answer:
Everything should simplify down to -9a-3 (your answer)
Step-by-step explanation:
Distributive property is basically <em>multiplying the outside number into the inside</em> parenthesis (). Basically #(a)--->#a or #(a+b)---> #a+#b
Since you're not ask to solve for anything but simplify, just multiply 3 to -3a and -1.....
so 3*-3a is -9a and 3*-1 is -3 and you have 3(-3a-1)= -9a-3
X equaks 105 becaus complementary= 180.
180-63=12+x
117-12=x
105=x
