Answer:
K
Step-by-step explanation:
techincally, I don't know if I am right, but there is more than one answer. The boundries/restrictions of what length DF could be are 2.477 < x < 8.477
-3(5/6)v - 1 = -6(3/4)
To start off, we can simplify by multiplying the fractions with their whole numbers.
-15/6x - 1 = -18/4
Further simplify
-5/2x - 1 = -9/2
Now we can multiply everything times 2 to get rid of the fractions
-5x - 2 = -9
Now we will isolate the x value. Add 2 to both sides.
-5x = -7
Finally, divide all by -5 to get the final answer.
x = 7/5
Hope I helped you out!
Answer:
<h2>d = 23</h2>
Step-by-step explanation:
∠IHE and ∠GHF are vertical angles.
Vertical angles have the same measures (are congruent).
Therefore, if m∠IHE = d + 44 and m∠GHF = 4d - 25, then we have the equation:
d + 44 = 4d - 25 <em>subtract 44 from both sides</em>
d + 44 - 44 = 4d - 25 - 44
d = 4d - 69 <em>subtract 4d from both sides</em>
d - 4d = 4d - 4d - 69
-3d = -69 <em>divide both sides by (-3)</em>
-3d/(-3) = -69/(-3)
d = 23
