If you multiply 36 by four since there are 4 wheels for skateboard
you will get 144. That number is the total number of wheels you need to order and since they come in packs of 20 what you need to do is divide 144 by 20 and you will get 7.2. So obviously you can't order 7.20 packs of wheels so this means that 8 packs of wheels must be bought in order to ensure that all of the skateboards get wheels on them.
The answer is 8.
664=60% off of original
percent means parts out of 100
60%=60/100=0.6
664=60% of original
'of' means multiply
translate
664=0.6 times originail
divide boh sides by 0.6
1106.666666=original
about $1106.67=original
or you could do ratio and proportion
664/60=x/100
answer is still $1106.67
Answer:
x=5
Step-by-step explanation:
20(20-x) = 300
Divide each side by 20
20/20(20-x) = 300/20
20-x = 15
Subtract 20 from each side
20-x-20 = 15-20
-x = -5
Multiply each side by -1
x = 5
