Answer:

x=5

Step-by-step explanation:

x-3x can be simplied to -2x and 3-9 can be simplied to -6

-2x+4=-6

Substract 4 from both sides

-2x=-10

Divide both sides by -2

Answer:

$x=5$

Step-by-step explanation:

$x-3x+4=3-9\\x-3x+4=-6\\-2x+4=-6$

Subtract 4 from both sides

$-2x+4-4=-6-4\\-2x=-10$

Multiply both sides by -1

$2x=10$

Divide both sides by 2

$x=5$

A mouse traveled a total distance of StartFraction 3 Over 24 EndFraction of a mile in a maze over the past 3 hours. The mouse tr

Artemon [7]

Step-by-step explanation:

It is given that, a mouse covered a distance of 3/24 miles over a distance of 3 hours. Each hour, the mouse traveled the same distance. Distance traveled in 1 hour can be calculated by dividing 3/24 miles by 3. So,

$d=\dfrac{\dfrac{3}{24}}{3}\\\\d=\dfrac{3}{24}\times \dfrac{1}{3}\\\\d=\dfrac{1}{24}\ \text{hours}$

Matt calculations shows that the distance is 3/8 hours. While dividing 3/24 by 3, he doesn't take reciprocal of 3 as a result he get 9 on numerator and 24 on denominator. Simplified fraction of 9/24 is 3/8. But the correct answer should be 1/24 hours.
