Answer:

Correct arrangement of equation of displacement to find a is as follows;

1-  Vt - d = 1/2 a t^2 (^ represents exponent i.e. t square as given in equation)

2- 2(Vt - d ) = a t^2

3- a = 2(Vt - d )/ t^2   (keep in mind, 2(Vt - d) whole divided by  t^2)

Step-by-step explanation:

1-  In the first equation, Vt is taken to the left side of the equation (keep in mind, original equation of displacement used for reference as given in question) and multiplied by -1 on the both sides of the equation.

2- In the second equation, 2 is multiplied on the both sides.

3- Multiply t^2 on both sides of the equation, We will get a in correct arrangement, which is required to find.

raketka [301]

Answer:

x \geq -21

Step-by-step explanation:

Let the number be x.

Translating the word problem into an algebraic equation, we have;

5(x + 27) \geq 6(x + 26)

Opening the bracket, we have;

5x + 135 \geq 6x + 156

Collecting like terms, we have;

6x - 5x \geq 135 - 156

x \geq -21
