Answer:
$ 2600 on Friday's game and $ 1456 on saturday's game.
Step-by-step explanation:
Let x be the money ( in dollars) earned on friday and y be the money ( in dollars ) earned on Saturday,
Since, total earning on friday and saturday is $ 4056.00,
⇒ x + y = 4056 -----(1),
Also, Friday's game generates $1144.00 less than Saturday's game.
⇒ y - x = 1144 -------(2),
Equation (1) + equation (2),
2y = 5200,
y = 2600
From equation (1),
x + 2600 = 4056
x = 1456
Hence, $ 2600 was taken on Friday's game and $ 1456 was taken on saturday's game.
Radio Barn : 200 + .15 x x = the weekly sales
Woofer: 300 + .10x
set them equal to find when they are them same
200 + .15x = 300 + .10x
subtract .10x from both sides
200 +.15x -.10x = 300 + .10x-.10x
200 +.05x = 300
subtract 200 from each side
200+.05x -200 = 300-200
.05x = 100
divide each side by .05
.05x/.05 = 100/.05
x =2000
The 2 jobs pay the same when the weekly sales are 2000 dollars
2. {x - 5 = -y}
{2y - 10 = -2x}
x-5 = -y
add 5 to each side
x = -y+5
multiply each side by -2
-2x = 2y -10
the 2 equations are the same, it has an infinite number of solutions
The system is dependent since the 2 equations are the same line
3. {2x = y - 7}
{4x - 2y - 14 = 0}
2x = y-7
subtract y-7 from each side
2x - (y-7) = 0
2x -y+7 =0
multiply by 2
4x -2y +14 =0
subtract the two equations
4x -2y +14 =0
4x - 2y - 14 = 0
---------------------------
28 = 0
since this cannot happen the lines will never cross ( parallel lines)
the system is inconsistent
Answer:
56
Step-by-step explanation:
10y+6
10(5)+6
10*5=50
50+6=56
