Answer:
75 + 25d > 250
d > 7
Step-by-step explanation:
Number of signatures needed : > 250
Amount of signatures ready = 75
Exoected number of signatures per day = 25
Number of days, d, needed signatures will be collected ;
Number of ready signatures + (expected number of signatures per day * number of days) > number of signatures needed
Mathematically,
75 + 25d > 250
25d > 250 - 75
25d > 175
d > 175 / 25
d > 7
So when one goes up, the other goes down. This is an inverse equation.
An inverse equation looks like this: y = 1/x
In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300
So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00
6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars
Answer:
lol idk my butthole stinke
Step-by-step explanation:
The coefficient 'a' for the quadratic term is a = 3
The coefficient 'b' for the linear term is b = -2
The coefficient 'c' is 0
Step-by-step explanation :
The given expression is,
To solve this problem we are using quadratic formula.
The general quadratic equation is,
Formula used :
Now we a have to solve the above equation and we get the value of 'x'.
a = 3, b = -2, c = 0
The coefficient 'a' for the quadratic term is a = 3
The coefficient 'b' for the linear term is b = -2
The coefficient 'c' is 0
Answer:
40 comic books
Step-by-step explanation:
Let x be the Jill comic books.
Given:
Jill sold half of her comic books and then bought sixteen more. She now has 36.
Therefore the algebraic equation of the given statement.
--------(1)
Now we solve above equation for x.
Subtract by 16 both side of the equation 1.
Multiply by 2 both side of the above equation.
Therefore, Jill had 40 comic books.
