writing systems of linear equations
define variables then solve the system

1.)two groups of students order burritos and tacos at a local resturant. One order of 2 burritos and 4 toacos costs $11.33. the other order of 9 burritos and 5 tacos costs $23.56. Find the cost of a burrito and the cost of a taco.
______________________________________________________
2.) Kendra owns a resturant. She charges $1.50 for 2 eggs and one peive of toast, and $.90 for one egg and one peice of toast. Write a system of equations to determine how much she charges for one egg and one peice of toast. Let x represent the number of eggs and y represent the number of toast.

3.) You decide to market your own computer software. You must invest $3,255 for computer hardware ans spend $2,90 to buy and package each disk. If each program sells for $13.75, how many copies must you sell to break even?

equation:
1/3 log (base 5) of (x+1) + 1/3 log (base 5) of (x-1)

do i move the 1/3 first then multiply (x+4) and (x-1) or vice versa?

equation:
log (base 3) of (x) + log (base 3) of (sqrt x+3) - 1/3 log (base 3) of (x-4)

thanks for the help.

I have to do my anatomy homework where I have to SPECIFICALLY label the bone of the foot and ankle. So I'm wondering if the metatarsals have a base, shaft and head. I know the proximal, middle, and distal phalanx of the digits do but I'm not sure about the metatarsals. THANK YOU!!!
