What is m∠abc? justify your reasoning.
> using the addition property of equality, 40 + 15 = 55, so m∠abc = 55°.
> using the subtraction property of equality, 40 − 15 = 25, so m∠abc = 25°.
> using the angle addition postulate, 15 + m∠abc = 40. so, m∠abc = 25° using the subtraction property of equality.
> using the angle addition postulate, 15 + 40 = m∠abc. so, m∠abc = 55° after simplifying.

table a is wierd

step-by-step explanation:

6*f

answer: i could not see part the question so ill explain how to get the answer

step-by-step explanation: for instance the distance she travele d is 10 and she traveled the same amout each mile so do 10 divided by how many miles she drove each time and you ge your answer.

a reflection across the x axis and a 90 degree rotation left and right.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
