<h3>For 22 kilometers, the two companies charge the same total fare</h3><h3>The total fare is $ 48</h3>

<em><u>Solution:</u></em>

Let "x" be the kilometers travelled

<em><u>For, Mr buchanan, the first cost $26 upfront and $1 per kilometer</u></em>

Therefore,

Cost : 26 + 1x ------- eqn 1

<em><u>The second costs $4 plus $2 per kilometer</u></em>

Therefore,

Cost : 4 + 2x -------- eqn 2

<em><u>For a certain driving distance, the two companies charge the same total fare</u></em>

Therefore, eqn 1 must be equal to eqn 2

26 + 1x = 4 + 2x

2x - 1x = 26 - 4

x = 22

Thus, for 22 kilometers, the two companies charge the same total fare

<em><u>What is the total fare?</u></em>

Substitute x = 22 in eqn 2

Cost: 4 + 2(22) = 4 + 44 = 48

Thus total fare is $ 48

Which solution to the equation 3/2g+8 g+2/g^2-16 is extraneous? A. g = –4 B. g = –4 and g = 16
ollegr [7]

im assuming the equation is:-

3 / (2g + 8) = (g + 2) / (g^2 - 16)

3(g^2 - 16) = (2g + 8)(g + 2)

3g^2 - 48 = 2g^2 + 4g + 8g + 16

Answer is A  x = -4

3g^2 - 2g^2 - 12g - 64 = 0

g^2 - 12g - 64 = 0

( g + 4)(g - 16) = 0

g = - 4, 16.

Test these solutions:-

g = -4  

left side = 3/0    which is indeterminate

right side = -2/0  indeterminate

So x = -4 is extraneous.

x = 16:- LHS = 0.075  RHS =  0.075  so x = 16 is a root.
