On the first day of the trip, Robert canoes for 3 hours. How far did Robert travel? I need help I don't know how to solve this please help

y-y1=4(x-x1)

step-by-step explanation:

this is point-slope form since you only have 4 as the slope it goes in place of m

hope this : )

let x be number of half-dollars and y be number of dimes

total value: 0.5x + 0.1y = 3.60

total amount: x + y = 24

solving this system of equations, we get that x = 3 and y = 21. (a proof of this fact has been left to the reader.) so there are 3 half dollars and 21 dimes.
