Answer: no solutions

Step-by-step explanation:

6x+4x-1=2(5x+4)

10x-1=10x+8

+1 +1

10x=10x+9

The equation is not true. It has no solutions.

1. Calculate the acceleration of riding her bicycle in a straight line that speeds up from 4 m/s to 12 m/s in 10 seconds. SOLUTI
valentina_108 [34]
<h3>✒️ACCELERATION</h3>

=================================

\large\sf\underline{Problem:}

Calculate the acceleration of riding her bicycle in a straight line that speeds up from 4 m/s to 12 m/s in 10 seconds.

=================================

\large\sf\underline{Answer:}

\qquad \qquad \huge \rm = 0.8 \: m/s²

=================================

\large\sf\underline{Solution:}

Here we have a given of,

  • \tt{(12\:m/s) \:= \:V_f = (final\: velocity) }
  • \tt{(4\:m/s)\:=\:V_i = (initial \: velocity) }
  • \tt{(10\:sec) \:=\:T = (elapsed time) }

\bold{Formula\:||\: Acceleration = \frac{v\: - \:v_0}{t} = \frac{ΔV}{ΔT} }

Because acceleration has a direction <u>(</u><u>riding her bicycle in a straight line</u><u>)</u>, it is important to always subtract the final velocity represented as \bold{V_f} from your initial velocity also represented as \bold{V_i}.

Now 'Work it out' and solve for Acceleration of riding her bicycle using the given formula.

  • \large\rm{A = \frac{V_f \:- \:V_i}{T} }
  • \large\rm{A = \frac{(12\:m/s\:-\:4\:m/s) }{10\:sec}}
  • \large\rm{A = \frac{ 8\:m/s}{10\:sec} }
  • \large\rm{A = 0.8\:m/s²}

Hence, The total acceleration of the girl riding her bicycle is 0.8 meters per second squared (m/s²).
