Answer:
See Explanation
Step-by-step explanation:
Given
10h+30+50j
Required
Factorize
The options of the questions were not give. However, I'll answer this question to give possible equivalent factors.
To factorize means, we reduce to lowest term.
Looking at individual unit of 10h+30+50j , one'll observe that 5 can divide through.
This gives
![5(\frac{10h}{5}+\frac{30}{5} +\frac{50j}{5})](https://tex.z-dn.net/?f=5%28%5Cfrac%7B10h%7D%7B5%7D%2B%5Cfrac%7B30%7D%7B5%7D%20%2B%5Cfrac%7B50j%7D%7B5%7D%29)
Simplify the expression in brackets
![5(2h + 6 +10j)](https://tex.z-dn.net/?f=5%282h%20%2B%206%20%2B10j%29)
Another factor can be gotten by dividing 10h+30+50j through by 10. This gives
![10(\frac{10h}{10}+\frac{30}{10} +\frac{50j}{10})](https://tex.z-dn.net/?f=10%28%5Cfrac%7B10h%7D%7B10%7D%2B%5Cfrac%7B30%7D%7B10%7D%20%2B%5Cfrac%7B50j%7D%7B10%7D%29)
![10(h + 3 +5j)](https://tex.z-dn.net/?f=10%28h%20%2B%203%20%2B5j%29)
Another factor can be gotten by dividing 10h+30+50j through by 2. This gives
![2(\frac{10h}{2}+\frac{30}{2} +\frac{50j}{2})](https://tex.z-dn.net/?f=2%28%5Cfrac%7B10h%7D%7B2%7D%2B%5Cfrac%7B30%7D%7B2%7D%20%2B%5Cfrac%7B50j%7D%7B2%7D%29)
![2(5h + 15 +25j)](https://tex.z-dn.net/?f=2%285h%20%2B%2015%20%2B25j%29)
Hence, the possible factors that can be gotten from 10h+30+50j are
![5(2h + 6 +10j)](https://tex.z-dn.net/?f=5%282h%20%2B%206%20%2B10j%29)
![10(h + 3 +5j)](https://tex.z-dn.net/?f=10%28h%20%2B%203%20%2B5j%29)
![2(5h + 15 +25j)](https://tex.z-dn.net/?f=2%285h%20%2B%2015%20%2B25j%29)
3 and what?
if it is 3 and 5 than the answer would be 15
Answer:
Adult = $7
Kids = $4
Step-by-step explanation:
Before we can find the price of the tickets, we first need to create expressions that can be used to explain the prices.
Let x = Price of kids tickets
Let y = Price of adults tickets
For this week the expression is:
3x + 9y = 75
For the last week the expression is:
8x + 5y = 67
Now to be able to find the value of x or y, we can use the Solving Linear Equations by Multiplying First Method.
3x + 9y = 75
8x + 5y = 67
Now we need to remove either the x or y by multiplying the whole expressions by a certain number.
8(3x + 9y = 75)
24x + 72y = 600
3(8x + 5y = 67)
24x + 15y = 201
Now that we have our equations and we can eliminate the x by subtracting both expressions.
24x + 72y = 600
<u>- 24x + 15y = 201</u>
57y = 399
To find the value of y, we divide both sides by 57.
![\dfrac{57y}{57}=\dfrac{399}{57}](https://tex.z-dn.net/?f=%5Cdfrac%7B57y%7D%7B57%7D%3D%5Cdfrac%7B399%7D%7B57%7D)
y = 7
Now that we have the value for y, we simply substitute the value in any of our expressions.
3x + 9y = 75
3x + 9(7) = 75
3x + 63 = 75
3x = 75 - 63
3x = 12
Now we divide both sides by 3 to find the value of x.
![\dfrac{3x}{3}=\dfrac{12}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7B3x%7D%7B3%7D%3D%5Cdfrac%7B12%7D%7B3%7D)
x = 4
So the ticket prices are:
Adult = $7
Kids = $4
