Y=- 6
Because the slope is 0, the equation would be y=0x+b
-6=0+b
b=-6
Let the number of songs Lou has = X
Kelly has 4 times as many as Lou, which would be written as 4X
Tiffany has 6 times as many songs as Lou, which would be written as 6X
The total number of songs = 682
You need to add all three people together to equal 682
So you would get:
X + 4X + 6X = 682 songs.
Combine all like terms ( 6x + 4x + X = 11x)
11x = 682
Now to solve for X divide both sides by 11:
x = 682 / 11 = 62
Lou = x = 62 songs.
Kelly = 4x = 4(62) = 4*62 = 248 songs.
Tiffany = 6x = 6(62) = 6 *62 = 372 songs.
The answer is 43j you just have to add them together
Answer: yards and meters
Step-by-step explanation:
Write an equation system based on the problem
For an instance, e stands for the price of a carton of eggs, and b stands for the price of a loaf of bread
"Kate bought 3 cartons of eggs and 5 loaves of bread for $30.07" could be written as 3e + 5b = 30.07 (first equation)
"Melissa bought 2 cartons of eggs and 2 loaves of bread for $14.74" could be written as 2e + 2b = 14.74 (second equation)
Solve the equation system using elimination method
Eliminate b to find e. To eliminate b, we should equalize the coefficient of b.
3e + 5b = 30.07 (multiplied by 2)
2e + 2b = 14.74 (multiplied by 5)
-------------------------------------------
6e + 10b = 60.14
10e + 10b = 73.70
------------------------- - (substract)
-4e = -13.56
e = -13.56/-4
e = 3.39
The price for a carton of eggs is $3.39
