At a bake sale, the cost, C or buying n pies is C = 7n. If one customer buys $84
worth of pies, how many did they buy? Use proper solution form.

A group of seven people went to an amusement park and spent $234 on tickets. If
a child's ticket costs $28 each and an adult ticket costs $37.50 each, how many
adult tickets and how many child tickets were purchased?
Answer:
3 adult tickets and 4 child tickets were bought.
Answer:
4 adult tickets and 3 child tickets
Step-by-step explanation:
So doing 234/7 gives you 33.428... which means its not all just children or adults. (I know that's common sense but it's best to do this anyway to further justify your answer)
The total cost for all 7 people shows that there must be an even amount of adult tickets to end up with a whole number so either 2, 4, or 6 adults.
2 adults = $75
4 adults = $150
6 adults = $225
Now we can use these possibilities to figure out if the left over child tickets added to the adult tickets would equal $234. (quick note: I am using # to show that it doesn't equal $234)
If 2 adults = $75, 5 children = $140, $140+$75 = $215 # $234
If 4 adults = £150, 3 children = $84, $84+$150 = $234
Now because we have already figured out that it would be 4 adult tickets and 3 child tickets, we wouldn't need to figure out 6 adult tickets and 1 child ticket, but, again, this would justify your answer and help to secure your marks.
If 6 adults = $225, 1 child = 28, $28+$225 = $253 # $234
I hope this answer helped you out and if you have any questions I'd be happy to help :)

I THINK I GOT IT OMG THAT WAS SO HARD
Answer:
z = 5
Step-by-step explanation:
[tex]\frac{4x^2y^7}{8x^3y^2} = \frac{y^z}{2x}[/tex]
It can be also written as -
[tex]\frac{2^2 \times x^2 \times y^7}{2^3 \times x^3 \times y^2} = \frac{1 \times x^0 \times y^z}{2 \times x^1 \times y^0}[/tex]
Using law of exponents , lets solve this.
[tex]=> 2^{(2-3)} \times x^{(2-3)} \times y^{(7 - 2)} = \frac{1}{2} \times x^{(0-1)} \times y^{(z-0)}[/tex]
[tex]=> 2^{-1} \times x^{-1} \times y^{5} = 2^{-1} \times x^{-1} \times y^z[/tex]
[tex]=> \frac{y^5}{2x} = \frac{y^z}{2x}[/tex]
[tex]=> y^z = y^5[/tex]

If 3x-7=5x, what is 6x?
Answer:
6x = - 21
Step-by-step explanation:
Given
3x - 7 = 5x ( subtract 3x from both sides )
- 7 = 2x
Then
6x = 3 × 2x = 3 × - 7 = - 21

if f(x) =2x-6 then f(1)=
Answer:
f(1) = -4
Step-by-step explanation:
Given that,
f(x) = 2x-6
We need to find the value of f(1).
Put x = 1 in the above expression.
f(1) = 2(1)-6
= 2-6
= -4
So, the value of f(1) is equal to -4.

The acceleration of an object varies directly as the force acting on it. If a force of 240 Newtons causes an acceleration of 150 m/s squared, what force will cause an acceleration of 100 m/s squared?
Answer:
The acceleration of an object varies directly as the force acting on it. If a force of 240 newtons causes an acceleration of 150 m/s², what force will cause an acceleration of 100 m/s?? 2. The stretch in a loaded spring varies directly as the load it supports.
Answer:
160 Newtons
Step-by-step explanation:
240÷150= 1.6. 100x1.6 gives us the answer which is 160 Newtons for 100m/s. For every 1.6 newtons,1 m/s is gained.
