Jane made a mistake when writing down a mutliplication , and she multiplied by 54 instead of 45. Her answer was 198 more than it
BARSIC [14]

Answer:

22

Step-by-step explanation:

Given that:

Let number multiplied by 54 = x

Let output = y

x * 54 = y + 198

x * 45 = y

54x = y + 198 - - - (1)

45x = y - - - (2)

Put y = 45x in (1)

54x = 45x + 198

54x - 45x = 198

9x = 198

x = 22

Number multiplied by 54 is 22

Are points A, C, D, and F coplanar? Explain.
tatiyna
Answer: Choice B) 

The points A, C and D form a triangle which is the front face you see in the pyramid. Point F is not on this triangle at all. Point F is towards the back at the base of the pyramid away from this front face. So we consider A,C,D,F collectively as a whole to be not coplanar. If we ignored the point F, then we can say that A,C,D are coplanar.
