2/3 = (approximately) 0.667
18 divided by 2/3 is approximately 26.98.
So, 27 pieces can be made.
Answer:
X=6
Step-by-step explanation:
First step isolate the variable;2x=12
Simplify;x=12/2=6
There are a total 40 cars
and there is x yellow cars
and there are nine times as much white cars (9x white cars) lol
so x+9x=40
simplify 10x=40
divide both sides by ten 10x/10=40/10
x=4
we are looking for the number of WHITE cars sooo we multiply by 9-
9x=36
how is this "hardddd" no offence*
sorry im a mean person
Answer:
y = 52 - 8x
Step-by-step explanation:
If he painted for 3 hours at a rate of 8 square meters per hour, the area painted was:
If after 24 squared meters painted, there are still 28 left, the total area is:
The area still left to paint is initially 52 squared meters and decreases at a rate of 8 square meters per hour, the function that describes the relationship between the area left to paint (y) and number of hours (x) is:
y = 52 - 8x
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
