Answer:
Step-by-step explanation:
Given
Represent the weight of the Jar with J and the sugar with S
Initially, we have:
After 2/3 of sugar is removed we have:
Required
Determine the weight of the jar
--- (1)
--- (2)
Simplify (2)
Take LCM
Make S the subject in (1)
Substitute 850g - J for S in
Multiply through by 3
Collect Like Terms
Make J the subject
<em>The jar weighs 370g</em>
Answer:
0.0001
Step-by-step explanation:
The value of the number is 0.0001. That presentation meets the format requirements for your literal.
You didn't specify how much is charged per ride to determine revenue...but we can just use a variable p for the price charged per ride...
r(x)=px, c(x)=15x+200
To break even, P, profit must equal zero and P(x)=r(x)-c(x)
P(x)=px-15x-200
P(x)=0 when x(p-15)-200=0
x=200/(p-15)
So the number of rides needed, x, can be found once you determine what is charged per ride. :D *note from even this partial answer that p must be greater than 15 or you will never break even.
Y=mx+b
4y=5x-12
y=5/4x-3
so you change your y intercept (-3) to your other y intercept (15)
y=5/4x+15
Since they tell us that Q is the midpoint you now understand that the line is split evenly.
PQ=QR
2x+3=3x-2
2x+5=3x
x=5.
