HELP!!! Will mark brainliest!!

Mathematics
1 answer:
yKpoI14uk [10]2 years ago
7 0

Step-by-step explanation:

BDC and ACD are complementary with each other. that means together they cover the full 180 degrees of the half circle that can be drawn on one side of a flat line.

180 = 11x + 25 + 4x + 5 = 15x + 30

150 = 15x

x = 10

BDC = 11x + 25 = 11×10 + 25 = 110 + 25 = 135 degrees

ACD = 4x + 5 = 4×10 + 5 = 40 + 5 = 45 degrees

mario62 [17]

Answer:

3 * 20s

Step-by-step explanation:

In order to find out how much Mr. Hartman will spend in total we first need to multiply the price of the keyboard and mouse by the number of computers in a single computer station. Once we have these products we add them together. Finally, we multiply this new value by 3 since there are a total of 3 computer stations. If we turn this into an expression it would be the following...

3 * (13.50s + 6.50s)

We can even simplify this by first adding the cost of the keyboard and mouse and then multiplying by s
