V=u+at to find the velocity, when the initial velocity is 3m/s
the acceleration is 1.5m/sx2
the time is 7 seconds

108 m/s

Step-by-step explanation:

Given,

Initial velocity ( u ) = 3 m/s

Acceleration ( a ) = 15 m/s^2

Time ( t ) = 7 seconds

To find : Final velocity ( v ) = ?

Formula : -

v = u + at

v

= 3 + ( 15 ) ( 7 )

= 3 + 105

= 108 m/s

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
