Answer:

(D) 7

Step-by-step explanation:

It is given that NELR is a parallelogram, then using the property of parallelogram, we have

{\angle}N+{\angle}E=180{\circ} (Sum of Corresponding angles of parallelogram is 180°)

7x+33+11x+21=180^{\circ}

⇒18x+54=180

⇒18x=126

⇒x=7

Therefore, the value of x will be 7.

Hence, option (D) is correct.

A private airplane leaves an airport and flies due east at 192 km/hr. Two hours later, a jet leaves the same airport and flies d
elixir [45]
The answer is 0.5 hours.

A velocity (v) of an object is a distance (d) divided by time (t):
v = d ÷ t                         ⇒                  t = d ÷ v

It is given:
v1 = 192 km/h
v2 = 960 km/h
t1 - t2 = 2h
We need to calculate t2.

Since they will travel the same distance before the jet overtakes the plane, we can say that d1 = d2 = d

Now, let's express t1 and t2:
t1 = d/192
t2 = d/960

Therefore: d/192 - d/960 = 2
The least common denominator is 960, so:
5d/960 - d/960 = 2
4d/960 = 2
4d = 2 · 960
4d = 1920
d = 1920 ÷ 4 = 480 km

Now t2 = d/960 = 480/960 = 0.5 hours.

3l=39
divide by 3
l=13

subsitue
t=2l
t=2(13)
t=26


tim has 26 and luke has 13
I don't know how many marble Tim has but probably all of them since alll must die and then the marbles go to Time
