![\bf \sum\limits_{n=2}^{10}~-2n-3](https://tex.z-dn.net/?f=%5Cbf%20%5Csum%5Climits_%7Bn%3D2%7D%5E%7B10%7D~-2n-3)
so, let's first change the bounds from 1 to 9, so we'll be dropping the indices by 1, in order to do the variable "n".
however, let's use a variable hmmm say "k", where "k" is the value of "n" beginning at 1, thus
k = n - 1.
however, if k = n - 1, then
k + 1 = n. So let's use those fellows then,
Answer:
Work backwards
Luis is 62 inches tall
maria is 1/3 taller than luis ( 62 + 1/3)
Maria is 62 1/3
Juan is 1 and 1/4 shorter than maria ( 62 1/3 - 1 1/4)
Answer: 61 1/12

The chef wants to make spaghetti and lasagna using more than 4000 g of pasta.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes :
Case 2: Sauce
chef wants to make spaghetti and lasagna using more than 5000 ml of sauce.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes:
Answer :
The two equations are :
For pasta:
For sauce:
