If I was solving this, which I suppose I am, my first step would be the clear the fractions by multiplying both sides by <em>a</em>.
That's there, first choice, SELECT IT
Then I'd bring the 5 to the other side;
Not among the choices.
Then I'd attempt to factor, looking for a pair that multiplies to 5 and adds to 8; no joy there.

All the other choices have nice rational answers so can't be right.
First choice only
Answer:
Q (8,0)
R (8,9)
S (5,0)
Step-by-step explanation:
I counted how many places is each point away from the line and then I counted the same amount of places on the other side in order to find the reflected angle.
Answer:
4
Step-by-step explanation:
calculate the sum 4*1 any expression is multiplied by 1 remains the same solution is 4
A. Eli's error was 3900-3867=33 kg.
B. A fairly small child would weigh about 33 kilograms.
C. Macy's percent error was .7/70=.01, or 1%. Eli's was 33/3900.0085, or .85%. Macy's percent error was larger, so Eli is more accurate.
Answer:
2
Step-by-step explanation:
first, add terms
8 + 5 + 12 + 4 + 5 + 8 + 7 = 49
seven terms, therefore we divide by 7
49/7 = 7
find distance
8-7= 1
7-5= 2
12-7=5
7-4=3
7-5=2
8-7=1
7-7=0
added together you get 14,
14/7 = 2
your answer is 2
hope this helps:)
