Answer:
x = -3
Step-by-step explanation:
55 + x + 74 + 54 = 180
x + 183 = 180
x = -3
In order to determine the number of pens present in the container, we need to set up equations from the given in the problem statement. We do as follows:
let x the number of pencils
y the number of pens
From the statement, 9 more pencils then pens in a container,
x = y + 9
From the statement, there are 25 writing utensils in the container in all,
x + y = 25
We use substitution method to calculate for x and y,
y + 9 + y = 25
2y = 16
y = 8
x = 17
Therefore, there are 8 pens in the container and 17 pencils.
Answer:c
Step-by-step explanation:
Profit maximization happens with marginal revenue is equal to marginal cost, so if Grant's assumption was right before selling the extra unit, when he actually sells the extra unit, this will increase his revenue
That's why the answer is c
Marginal revenue will exceed marginal cost
X+3y=3
First add subtract the x
3y=-x+3
Then divide 3
Y=-1/3x+1
The slope is the coefficient of x, which is 10, and the y-intercept is the constant, which is 5.
