Answer: I think it would be 1/2, 2/2 or 2/5. If i'm wrong then i'm sorry.
Step-by-step explanation:
25x+5x +50
combine like terms
30x+50
isolate x
30x=-50
divide by 30
x= -1&2/3 or roughly -1.67
Answer:
Step-by-step explanation:
You don't need the Law of Cosines, the Law of sines if what you need. You can't use the Law of Cosines because in order to find side a, you would need the length of side c and you don't have it. Using the Law of Sines is appropriate, knowing that angle B = 55:
and solving for a:
so
a = 143.0
Answer: The distance between a and c is 8 units
Step-by-step explanation:
You can count the number of units they are apart, but if there isn’t a grid, then do this:
If x or y values in the ordered pairs are different, subtract them from each other and find the absolute value of the difference. (It’s my own rule, so there is a better method. My explanation apples only to ordered pairs that share a x or y value, like A and C)
2-(-6) = 8, and the absolute value of 8 is 8
Or
(-6)-2 = (-8), and the absolute value of -8 is 8 (You’ll get the same answer)
