Find the value of x if a, b, and c are collinear points and b is between a and c.
ab=5x−1,bc=14,ac=25−x

x = 2

Step-by-step explanation:

Collinear means that the points A, B and C all lie in a straight line, hence

AB + BC = AC, substitute values

5x - 1 + 14 = 25 - x

5x + 13 = 25 - x ( add x to both sides )

6x + 13 = 25 ( subtract 13 from both sides )

6x = 12 ( divide both sides by 6 )

x = 2

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
