Answer:
(1, -2)
Step-by-step explanation:
Subtracting the first equation from the second gives ...
(5x +y) -(3x +y) = (3) -(1)
2x = 2 . . . . . collect terms
x = 1 . . . . . . . divide by 2
Then substituting into the first equation, we have ...
3·1 +y = 1
y = -2 . . . . . . subtract 3
The solution is (x, y) = (1, -2).
Answer:
x = -3, y = -0.512
x = -1, y = -3.2
x = 0, y = -8
x = 2, y = -50
Step-by-step explanation:
Answer:
8y+96
Step-by-step explanation:
8(y+12)
First, do 8*y which is 8y
Now, 12*8=96
So, the answer is 8y+96
Answer:
40b - 4b or 36 b
Step-by-step explanation:
No. of tomatoes in each box = 40
No. of box shipped = b
No. of tomatoes in those b box = b*No. of tomatoes in each box = 40b
No. of tomatoes damaged in each box = 4
No. of box shipped = b
No. of tomatoes damaged in those b box = b*No. of tomatoes damaged in each box = 4b
Thus, total no. of tomatoes that can be sold by store = No. of tomatoes in those b box - No. of tomatoes damaged in those b box = 40b - 4b
Algebraic expression to express the no. of tomatoes that can be sold from those b box is
40b - 4b = 4b(10-1) = 4b(9) = 36b (Answer)
