(a) Let <em>x</em> = 3.12333…. Then 100<em>x</em> = 312.333… and 1000<em>x</em> = 3123.333…, so that
1000<em>x</em> - 100<em>x</em> = 3123.333… - 312.333…
==> 900<em>x</em> = 2811
==> <em>x</em> = 2811/900 = 937/300
(b) <em>x</em> = 4.38555… ==> 100<em>x</em> = 438.555… and 1000<em>x</em> = 4385.555…
==> 900<em>x</em> = 3947
==> <em>x</em> = 3947/900
(c) <em>x</em> = 37.222… ==> 10<em>x</em> = 372.222…
==> 9<em>x</em> = 335
==> <em>x</em> = 335/9
(d) <em>x</em> = 16.292929… ==> 100<em>x</em> = 1629.292929…
==> 99<em>x</em> = 1613
==> <em>x</em> = 1613/99
(e) <em>x</em> = 2.333… ==> 10<em>x</em> = 23.333…
==> 9<em>x</em> = 21
==> <em>x</em> = 21/9 = 7/3
Answer:
x=12.5
Step-by-step explanation:
2x-25=0
Move 25 to the right with addition so you get the 2x by itself:
2x=25
Now divide the 2 to the right to get the x by itself:
x=25/2, which is the same as x=12.5
This is in fact a polynomial of degree 7 since 7 is the highest exponent. Written correctly, these would be in order from highest degree to lowest. The coefficient (or number) that goes with the 7th degree term is a 6.
Answer:
18000 ft
Step-by-step explanation:
1 yd = 3 ft
Using conversion factors
