Pretty sure that it is the first answer, the one with the back point between 6 & 8
We can say that x is the amount of time of the first (easier) part of the hike. Ans t is the amount of time of the second ( more difficult ) part of the hike.
x = 2 - t
And:
3 x + 1.5 t = 5
Answer:
The equation is:
3 * ( 2 - t ) + 1.5 t = 5
We can also solve this equation:
6 - 3 t + 1.5 t = 5
1.5 t = 1
t = 0.66 h = 2/3 h = 40 min.
The missing statement and reasons are;
<u><em>Statement 5; 12x + 20 = 11x + 23
</em></u>
<u><em>
Reason 2; Vertically opposite angles are equal
</em></u>
<u><em>
Reason 4; Transitive property of equality.
</em></u>
<u><em>
Reason 6; Subtraction Property of Equality.</em></u>
We are given that;
∠BDA ≅ ∠A
We want to prove that; x = 3
Statement 1; ∠BDA ≅ ∠A
Reason; It is Given
Statement 2; ∠BDA ≅ ∠CDE; The statement means they are congruent and equal.
Reason; Vertically opposite angles are equal
Statement 3; ∠CDE ≅ ∠A; This means ∠CDA is congruent to ∠A.
Reason; Transitive property of congruence.
Statement 4; m∠CDE = m∠A. We saw that ∠BDA ≅ ∠A and ∠BDA ≅ ∠CDE. Thus, by transitive property of equality, we can say that; m∠CDE = m∠A.
Reason; Transitive property of equality.
Statement 5; 12x + 20 = 11x + 23
Reason is; Substitution property of equality
Statement 6; 12x = 11x + 3; In statement 5 above, what was done to get this statement 6 was to subtract 20 from both sides. This is known as subtraction property of equality.
Reason; Subtraction Property of Equality.

To find the time to reach ground solve -16t^2 +55 = 0
t^2 = 55/16
t = sqrt55 / 4 = 1.85 seconds
I think it’s c I’m not sure tho hopefully it helps
