Answer:
y = -13
Step-by-step explanation:
5y + 2(y - 2) = 8y - 3(7 - 10)
5y + 2y - 4 = 8y - 21 + 30
7y - 4 = 8y + 9
-4 = y + 9
-13 = y
y = -13
Answer:
30
Step-by-step explanation:
pythagoras theorem dictates:
a squared plus b squared=c squared
576+324=900
take the square root of that

Answer:
JL = 52
Step-by-step explanation:
It is given in the question that K is the midpoint of JL.
So, JK = KL ......... (1)
Now, given that, JK =3x - 1 and KL = 2x + 8
Therefore, from equation (1), we can write
3x - 1 = 2x + 8
⇒ x = 9
So, JK = 3x - 1 = 3(9) -1 = 26 and KL = 2x + 8 = 2(9) + 8 = 26
Hence, JL = JK + KL = 26 + 26 = 52. (Answer)
The answer is A
hope this helps
