Help me please/yuigigkhohlj
bogdanovich [222]

We have: PZ = 1/2 XZ ( Z is the middle point of XZ )

=> 22 = 1/2(5x - 11)

=> 1/2(5x - 11) = 22

=> 5x - 11 = 22 : 1/2

=> 5x - 11 = 44

=> 5x = 44 + 11

=> 5x = 55

=> x = 55/5 = 11

ANSWER: x = 11

Ok done. Thank to me :>

Answer:

Solving the given formula for v2 gives us:

a(t_2-t_1)+v_1 = v_2

Step-by-step explanation:

Solving an equation for a particular variable means that the variable has to be isolated on one side of the equation.

Given equation is:

a = \frac{v_2-v_1}{t_2-t_1}

Multiplying both sides by t2-t1

(t_2-t_1) . a = \frac{v_2-v_1}{t_2-t_1} . (t_2-t_1)\\a(t_2-t_1) = v_2-v_1

Adding v1 to both sides of the equation

a(t_2-t_1)+v_1 = v_2-v_1+v_1\\a(t_2-t_1)+v_1 = v_2

Hence,

Solving the given formula for v2 gives us:

a(t_2-t_1)+v_1 = v_2
