Twice a number would be 2x reduce means minus and equal to 5x because times the same number is increased means added by 9
answer is
2x-3=5x+9
For this case we have the following expression:
8 + 0 = 8
The sum has several properties.
One of them is the following one:
Neutral element: the sum has a neutral element that is 0. If you add 0 to any number the result is the same number.
Answer:
The property shown in the given expression is:
Neutral element.
Answer:
$6.90
Step-by-step explanation:
Apparently the cost function for the Oyster is ...
c(n) = 90,000 +5.40n
Then the cost for 60,000 units is ...
c(60,000) = 90,000 +5.40·60,000 = 414,000
In order to break even, Sackville Plastics must sell these for ...
$414,000/(60,000 units) = $6.90/unit
Answer:

Answer:
One number is 561
The other number is 23.6854
Step-by-step explanation:
x = y^2 One number = the square of another
x + y^2 = 1122 The sum of the two numbers is 1122
Substitute y^2 in for x on the second equation.
y^2 + y^2 = 1122 Combine like terms on the left
2y^2 = 1122 Divide by 2
y^2 = 1122/2
y^2 = 561 Take the square root of both sides.
y = 23.6854
x = y^2
x = 561
y^2 = 561
