Answer:

x=-18

Step-by-step explanation:

What you have do do is look at the word <em>difference. </em>

Difference means subtraction so you will subtract x and -37.

x-(-37)=19. You will then make the negative a positive and subtract 37 from both sides.

x=-18 is your answer.

Noon is 12, I'm guessing you mean both of these at am, or both at pm. 12-3 is 3 hours, but there's 5 extra, so the elapsed time would be 3:05.

Since it’s supplementary the straight line would equal to 180 degrees

4d - 1 + 105 = 180
4d + 104 = 180
4d = 76
d = 19

Answer:

0.03125

Step-by-step explanation:

If we have a fair coin the probability of landing a head is 50%.

We can think the question as what is the probability of landing four tails and then a head. That is we needed at least 5 tries to get a head.

$Prob \{ T,T,T,T,H\}$

Since this events are independent we can write it as

$Prob \{ T\} \times Prob \{ T\} \times Prob \{ T\} \times Prob \{ T\} \times Prob \{ H\} =.5^5= 0.03125$
