2/5 4/10 6/15 8/20 10/25 12/30 are all equivalent to 2/5
Answer:
x = 15 or x = -19
Step-by-step explanation:
ΔPQR similar to ΔSQT
SQ / QP = ST / PR
8 / 8+x+5 = x-9 / 21
8 / 13+x = x-9 / 21
(x+13)(X-9) = 168
x² + 4x - 117 = 168
x² + 4x - 285 = 0
(x - 15) (x + 19) = 0
x = 15 or x = -19
If you figure out the base rate of the gas by dividing the cost by the gallon, you would find out that it is 2.892, which rounds to 2.89. Multiply that by 16 and you have your answer at 46.24.
Hope this helps.
The answer is 14.13 I think cause I had that answer before and I put 14.13 and it was right so it's 14.13 :)
