Hi there!

If KLM is an isosceles triangle, then KM = LM.

4d - 13 = 12 - d

Solve for d. Add 'd' to both sides:

5d - 13 = 12

Add 13 to both sides:

5d = 25

Divide both sides by 5:

<u>d = 5 units.</u>

Solve 3x - 9x + 7 - 3 = -8.<br><br> 6<br> -6<br> 2<br> -2
alexgriva [62]

Answer:

x=2

Step-by-step explanation:

  1. add like terms (3x-9x= -6x, 7-3= 4)
  2. then move the constant to the right (-8+4=-12)
  3. finally divide it by 6 which gives you "x"

Cylinder a has a mass of 3 kg and cylinder b has a mass of 8 kg. Determine the speed of a after it has moved 2 m starting from r
german

The rate of change of an object's velocity with respect to time is defined as acceleration. The speed of a after it has moved 2m starting from rest is 1.98 m/s².

<h3>What is acceleration?</h3>

The rate of change of an object's velocity with respect to time is defined as acceleration. Vector quantities are accelerations. The orientation of an object's acceleration is determined by the orientation of its net force.

We can see that the acceleration of 3kg mass is double that of the 8kg mass. Therefore, Writing the force conservation equations altogether,

(T - 3g)/3 = 2(8g - 2T)/8

T= 3.6*g

Now, the Acceleration of 8kg mass can be written as

a = (8g - 2T)/8

  = 0.8g/8

  =0.1g

Therefore, acceleration of mass 3kg = 2×a = 0.2g

Further, as per the law of motion we can write,

v² - u² = 2as

Substituting the values, u =0; a=0.1g; s=2m; we will get,

v=1.98m/s

Hence, the speed of a after it has moved 2m starting from rest is 1.98 m/s².
