2x is the smaller angle degree
since the 5 is a negative you are actually subtracting it from 3
so 3 +(-5) is actually 3-5. which = -2
Answer is -1/2
Parallel lines both have the same gradient or slope
So the line parallel to the one in the diagram will have the same gradient, just that they will have different y-intercepts.
The answer is 3 hours and 45 minutes
Hope it helps
Answer:
81
Step-by-step explanation:
9*(x + y) = 10x + y
9x + 9y = 10x + y
0 = x - 8y
8y = x
=======
y = 1
x = 8
x + y = 8 + 1 = 9
9*9 = 81
So 81 is 9 times the sum of it's digits.
