Answer:
Step-by-step explanation:
x+3y=1
You would do 12 divided by 25 which equals 0.48 and keep on doing that the next one is 0.52 and last is 0.53 meaning the best is the 12 muffins
Answer:
6.6 miles
Step-by-step explanation:
due to the construction with the 3 parallel lines, the two crossing lines create 2 similar triangles (same angles and all side lengths and all other lines are all determined by the same multiplication factor going from one triangle to the other).
so,
LM = KL × f
MP = HK × f
HL = LP × f
KL = LM × f
and so on.
and then, also
JL = LN × f
the other thing we know due to the construction (L will always be connected with the middle of HK and MP) : the triangles are isoceles triangle (2 equal sides). in fact, because HK = HL = 2 miles, and it is an isoceles triangle, we also know that KL = 2 miles too.
so, we have
KL = LM × f
2 = 6 × f
f = 2/6 = 1/3
and therefore
JL = LN × f
2.2 = LN × 1/3
LN = 2.2 / 1/3 = 2.2 × 3/1 = 2.2 × 3 = 6.6
so, LN is 6.6 miles long.
Answer:
4
Step-by-step explanation:
(9 x 2/3) x 2/3
9x 2 = 18
18/3 = 6
6 x 2 = 12
12/3 = 4
(9 x 2/3) x 2/3 = 4
