4x - 3y + 20 = 0....4x - 3y = -21
4x - 3y = -21.....multiply by -2
5x - 6y = -25
----------------
-8x + 6y = 42 (result of multiplying by -2)
5x - 6y = -25
---------------add
-3x = 17
x = -17/3
this system of equations has 1 solution
Answer:
Side-side-side postulate
Step-by-step explanation:
In the first statement, we are given that AC = BD ....... (1){It is given}
Now, in the second statement, we are given that AB = DC ...... (2){ Because the parallelogram has equal opposite sides}
Now, again we are given that AD = DA ........... (3) {From the symmetric property}
Now, conditions (1), (2), and (3) are applicable to say that Δ ABD and Δ ACD are congruent.
Since there are three sides involved to say Δ ABD ≅ Δ ACD, so it is by Side-side-side postulate. (Answer)

Answer:
t > 30
Step-by-step explanation:
In terms of t, Lena's exercise time can be described by "t is more than 30". In math terms, that's the same as "t is greater than 30":
t > 30
