Step-by-step explanation:
Answer:
cost of ribeye steak dinners = $10.36
cost of grilled salmon= $11.581
Step-by-step explanation:
Let the cost of one steak dinners be x
Let the cost of one grilled salmon be y
One a particular day the waitress sells 12 ribeye steak dinners and 39 grilled salmon for a total is $575.53 which can be written in equation as
12(x)+39(y)= $575.53-------------------------------------(1)
On another day she sells 25 ribeye steak dinners and 13 grilled salmon dinners totals to $582.43.This can be represented as
25(x)+ 13(y)= $582.43-------------------------------------(2)
solving the equation (1) and (2)
eq(1) x 1
eq(2) x 3
-------------------------(3)
Subtracting these equation we get,


x= 10.36
Now substituting this in equation (1)




y=11.581
Answer:
Yes! See explanation below!
Step-by-step explanation:
If a positive and negative number is equivalent, then they are called additive opposites meaning they add up to 0, basically cancelling out.
Ex:

Answer: 17
Step-by-step explanation:
y= 1
(3y + 2)(7y)
(3(1) + 2(7(1)) Replace y with given number
(3 + 2(7)) Multiply 1 to 3 and 7
(3 + 14) Multiply 2 and 7
(17) Add 3 and 14
