Using the speed - distance relationship, the time left before the appointed time is 27 minutes.

<u>Recall</u><u> </u><u>:</u>

  • Distance = speed × time

  • Let time = t

<u>At</u><u> </u><u>10mph</u><u> </u><u>:</u>

  • Distance = 10 × (t + 3) = 10t + 30 - - - (1)

<u>At</u><u> </u><u>12</u><u> </u><u>mph</u><u> </u><u>:</u>

  • Distance = 12 × (t - 2) = 12t - 24 - - - - (2)

<em>Equate</em><em> </em><em>(</em><em>1</em><em>)</em><em> </em><em>and</em><em> </em><em>(</em><em>2</em><em>)</em><em> </em><em>:</em>

10t + 30 = 12t - 24

<em>Collect</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em>

10t - 12t = - 24 - 30

-2t = - 54

<em>Divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>-</em><em> </em><em>2</em>

t = 54 / 2

t = 27

Hence, the time left before the appointed time is 27 minutes.

Solve the following equation for x. Show each step. <br> 5x + 2 = 3x + 4(2x - 1)
Reptile [31]

Answer:

x=1

Step-by-step explanation:

Start with:

5x+2=3x+4(2x-1)

Distribute the 4 into (2x-1):

5x+2=3x+8x-4

Combine like terms:

5x+2=11x-4

Add 4 to both sides of the equation:

5x+6=11x

Subtract 5x from both sides of the equation:

6=6x

Divide both sides of the equation by the coefficient of x, which is 6:

1=x

or

x=1
