They want to make a total of $1200.
55*10=550
55*8=440
440-550=990
1200-990=210
210/35=6
So they should sell the other plants for $6 each.
Answer:
The equation is 1/2 x + 8 = 15 ⇒ answer A
Step-by-step explanation:
* Lets explain how to solve the question
- Grace and her dad are planning to attend the state fair
- The price of an adult ticket is $15
- The price of the adult ticket is one half the price of the student ticket
plus $8
- Assume that the price of the student ticket is x
∵ The price of the student ticket is x
∵ The price of the adult ticket is half the price of the student ticket
x plus 8
- lets multiply half by x and then add the result by 8
∴ The price of the adult ticket = 1/2 x + 8
∵ The price of the adult ticket is $15
- Equate the expression of the price of the adult ticket by the price of
the adult ticket
∴ 1/2 x + 8 = 15
* The equation to determine how much Grace will pay for a student
ticket is 1/2 x + 8 = 15
∴ The answer is choice A
X*.04 = 56
x = 56/.04
x = 1400
(* means "times")
Answer:
f(-5)=30
Step-by-step explanation:
in this scenario you want to plug in -5 for x which will give you an equation of f(-5)=(-5)^2+5 which evaluates to 30
It will take 1 minute to tub to drain to his desired level, by Rate of change.
What is rate of change?
Rate of change is used to mathematically describe the percentage change in value over a defined period of time.
Given, starting water value = 42 and desired water level = 28
Rate of change = 14 gallons.
Let x be the time,
According to question,
42-14x=28
-14x=-14
x=1
Hence, it will take one minute.
