Answer:
x=0
y=3
Step-by-step explanation:
y =7x+3 equation 1
7x-6y=-18 equation 2
using equation 1 in equation 2 we have:
7x-6(7x+3)= -18
7x -42x -18 = -18
-35x -18 = -18
-35x = -18 +18
-35x=0
x=0
so we have:
y =7x+3
y= 7(0) +3
y = 3
I’m pretty sure it’s 1.99
Answer:
y = root 9
Step-by-step explanation:
1/2 is equivalent to the root of something.
The root of y equals 3.
Therefore, y would be equal to root 9, as root 9 is equivalent to 3.
Hope this helps :)
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
