Solve the equation <br> 14(3x-1)=2x-23

irina1246 [14]

Answer:

$x=\frac{-9}{40} \\$

Step-by-step explanation:

Given Equation:

$14(3x-1)=2x-23$

Solving the bracket on L.H.S

$(14)(3x)-1(14)=2x-23$

$42x-14=2x-23$

Taking the terms of 'x' to one side and the constants to other side

$42x-2x=-23+14\\\\40x=-9\\\\x=\frac{-9}{40} \\$

The value of 'x' after solving the equation is:

$x=\frac{-9}{40} \\$

Alekssandra [29.7K]

Answer:

Step-by-step explanation:

The train traveled half a mile.

1 mile = 5280 ft

0.5 mile = 0.5 * 5280 ft = 2640 ft

A time from 10 sec to 55 sec is 55 sec - 10 sec = 45 seconds.

2640 ft in 45 seconds

speed = distance/time

speed = 2640 ft / 45 sec = 58.6666... ft/sec

Answer: speed = 58.7 ft/sec
