Answer:
x= -3
Step-by-step explanation:
simplify.
1+4=x-8
Move all terms containing x to the left
1+3x=-8
Move all terms NOT containing to the right

Step-by-step explanation:
(i hope this helps)
speed=distance/time taken
3/4=x/60 so you divide 60 by 4 and get 15x3=45/60
Simple, convert it to a decimal, first
move the decimal two places to the left
45%

0.45.
Then you change it into a fraction
45/100.
But, you can simplify it even more by dividing the numerator and denominator by 5.
45/5=9
and
100/5=20
Thus, it would be simplified, 9/20.
