Answer:
B. 10
Step-by-step explanation:

Answers:
x = 57
y = 86
z = 37
=================================================
Work Shown:
x+123 = 180 .... since x and 123 form a straight line
x = 180-123
x = 57
y = 86 since the y and 86 angles are vertical angles
-------
For any triangle, the three angles always add to 180. So,
x+y+z = 180
57+86+z = 180
143+z = 180
z = 180-143
z = 37
As a check,
x+y+z = 57+86+37 = 180
which confirms the value of z
Answer:

Step-by-step explanation:
|-32|
Absolute values means take the positive value of
|-32| = 32
We were given the distance, d as a function of time, t.
.
To find
, we put
, in to

This implies that,


This means that in 15 seconds light covers a distance of 4,500,000 kilometers
Answer:
4. $130.50
Step-by-step explanation:
Sorry, but I only know for no.4 which is $130.50.
Explanation: 18 hours is 20 percent more than 15 hours.
So all we have to do is multiply 1.2 to 108.75, since multiplying 1.2 is the equivalent to 20 percent.
Which then is why I get the answer of $130.50.
