Answer:
DF = 3 , ∠B = 28° , ∠P = 105° , QR = 11.6 , ∠M=45°,LN = 8.5
Step-by-step explanation:
As ΔABC≅ΔDEF ,
DF = AC and ∠B = ∠E because corresponding parts of congruent triangles are equal.
∴DF = 3 and ∠B= 28°
In the next part,
as ΔLMN≅ΔPQR,
∠P = ∠L , QR = MN , ∠M = ∠Q , LN = PR as corresponding parts of congruent triangles are equal.
∴∠P = 105° , QR = 11.6 , ∠M = 45° , LN = 8.5
Given

first, convert

to base 25 to match the other term.



Substitute above identity into original equation:

Use substiution

above equation becomes
2/u-3u=1
multiply by u and solve for u:

=> u=2/3 or u=-1
case A:. u=2/3 =>

=>

case B: u=-1 =>
which does not give a real solution, so reject.
See graph below for confirmation of solution.
BBB it is b the answer is b
Answer: the answer would be 4.5
Step-by-step explanation:
she walks 3 miles every 80 minutes and 80 plus 80 would be 160 but this is 120 so it would be 80 plus 40 so its half of 80 so half of 3 is 1.5 so there, hopes this helps
