Question 647303: Can you help me solve this, the legnth of a table is a 1 foot greater than its width. The perimeter is less than 14ft. Describe the demensions of the table. I have to put this into an inequality problem but I don't know how to.
My second problem is, a baker needs between 30lbs and 40lbs of flour-sugar mixture that contains 10 times as much flour as sugar. What are the possible weights of flour the baker can use?

1st problem:
let x=width
length=x+1
perimeter=2(width+length)
2(x+x+1)<14
4x+2<14
4x<12
x<3
..
2nd problem:
let x=lbs of sugar
10x=lbs of flour
30<10x+x<40
30<11x<40
30/11 < x < 40/11
300/11<10x<400/11
possible weights of flour the baker can use= 300/11 and 400/11 lbs≈27.3 and 36.4 lbs
