The sum of the rational expression is
X=4
Answer=103 ounces
First we need a conversion equations to get from pounds to ounces
1pound=16ounce
2pounds=2*16=32 ounces of cucumber
3pounds=3*16=48 ounces of lettuce
Now that all of the vegetables are in ounces, we can solve for their total weight.
x=32+8+48+15=103 ounces
He bought 103 ounces of vegetables in total.
Answer:Hi,
Let the number be x
Twice the number is 2x
Five less than twice the number is 2x-5, which is given as 9
Therefore, 2x-5 = 9
or, 2x = 9+5
or, 2x = 14
or x=7
Thus the number is 7.
