Y=mx+b is the equation we must fill out, with x and y being their respective coordinates, m being the slope, and b being the y-intercept. The y intercept will be at (0, y), and the beginning of this problem already gives us the y-intercept: -4.
We now know y=mx-4. To find the slope, m, we’ll plug in one of the coordinates: (5, 1). The new equation is 1=m(5)-4. Solve this to get 5=m(5), and then m=1.
Now that we know the slope and y-intercept, we can conclude that the equation is y=x-4.
Answer: 150 coins
Step-by-step explanation: let the number of captain Sparrow and the crew = c
The number of gold = g
This mean each person will get g/c
If there were four fewer pirates, then each person would get 10 more coins means
g/(c - 4) = g/ c+ 10
cg = (c-4)(g+10c) ....... (1)
However, if there were 50 fewer coins, then each person would get 5 fewer coins.
(g - 50)/c = g/c - 5
g - 50 = g - 5c
5c = 50
c = 10
Substitute c in equation 1
cg = (c-4)(g+10c) ....... (1)
10g = (10 - 4)(g + 10×10)
10g = 6× (g + 100)
10g = 6g + 600
4g = 600
g = 150 gold coin.
Therefore they dig up 150 gold coin

Step-by-step explanation:
Answer:
18.9/29 or 65.17% of the coal.
Step-by-step explanation:
3/29 x 6.3 = 18.9/29
18.9/29 = 0.6517 x 100 = 65.17
