Answer: 20%
Step-by-step explanation:
20% black dresses or suits
.35 = 35% wearing brown
1/4 = 25% wearing navy
100% -20% - 35% - 25% = 20% left
First convert the length of the board into centimeter:
2.5m=250cm,because 1m=100cm
x-use the unknown sign for the first shelf
(x*2)+18-As the second shelf is 18cm longer than twice the length of the first one
x-12-as the third shelf is 12cm shorter than the first shelf
x+4-as the remaining(forth) shelf is 4cm longer than the first shelf
Add up all terms and the result is 250 on the other side of equal sign,solve it:
x+(2x+18)+(x-12)+(x+4)=250
transfer like terms on one side and the other ones on the other side
x+2x+x+x=250-18+12-4
add the like terms up
5x=240
divide 240 with 5 as it is transferred on the other side
x=240/5
finally-the result for the first shelf
x=48
apply the result of the first shelf to get the result of the second shelf
(48*2)+18=96+18=114
I know that it is too long,but I hope that it will help you.. :-)
