1. For Trish's Home Economics Class project she decided to make her own homemade trail
mix. She bought 7 lbs. of peanuts that cost $4.00 per pound, 5 lbs. of raisins that cost $2.75
per pound and 10 lbs. of M&Ms that cost $3.63 per pound. She mixed all of the three
ingredients together and made individual 1 lb. bag treats to hand out at school. What would
be the cost per pound of the mixed treats?

9. (y^-5)^10y^10 a. y^-60 b. y^60 c. y^-150 d. y^150 find the simplified form of each expression. 10. (4/7^5)^2 a.8/14^10 b.16/49^25 c.16/49y^10 d.8/14y^25 11. determine if the number 3.43 times 10^-6 is written in scientific notation. if not, explain. a. yes; the number is written scientific notation. b. no; the first factor is not a number between 1 and 10. c. no; it is not written as a number times a power of 10

What expression is equivalent to 1/2(2+3x-6)

Solve: 3x+y=6 4x-2y=18 show all work !
