Answer:
Step-by-step explanation:
Answers are explained/Solved in the attach document.
To get the price, you have to multiply the amount by the percent it would become.
100% of 39 is 39
It is 33% off
100 (1.00) - 33 (0.33) = 67% (0.67)
Remember, the percent is a decimal because it is part of a whole (1).
39*0.67=$26.13.
Answer:
391
Step-by-step explanation:
First you must make the fraction a decimal so you can use it in an equation.
To do so move the . over to the left twice.
.68
Now multiply 575 by .68
575 x .68=391
Distance=speed times time
if they take the same time, we cal the time , t
b=bike speed
w=walking speed
bikedistnace=17=bt
walkdistance=9=wt
b is 4 more than w
b=4+w
we have
17=bt
9=wt
b=4w
ok so
multiply first equation by 9 and 2nd by 17
153=9bt
153=17wt
set equal
9bt=17wt
divide both sides by t
9b=17w
sub b=4+w for b
9(4+w)=17w
distribute
36+9w=17w
minus 9w both sides
36=8w
divide both sides by 8
4.5=w
he walks 4.5kph
