Kevin bought fish at a grocery store at $5.  per pound for salmon and $3.00 a pound for catfish.  He spent a total of $36.60 on salmon and catfish.  If Kevin bought a total of 10 pounds of salmon and catfish at the grocery store, how many pounds of each did he buy?

I think its that Kevin bought 3.3 lbs of salmon and 6.7 lbs. of catfish..

Step-by-step explanation:

because

x+y=10

5x+3y=36.60

3x+3y=30.00

2x=6.60

x=3.3

y=6.7

hope i helped you! :) <3

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
