Answer:
y = ![\frac{6-4x}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B6-4x%7D%7B9%7D)
Step-by-step explanation:
In equations, it's important to complete an operation to both sides because if it is only completed on one then the whole equation will change and the solution will be different so it's an important rule to remember when solving equations that you have to keep the equation balanced.
→ 6 = 4x + 9y
⇒ Minus 4x from both sides to isolate 9y
→ 6 - 4x = 9y
⇒ Make 'y' the subject
→ 9y = 6 - 4x
⇒ Divide both sides by 9 to isolate 'y'
→ y = ![\frac{6-4x}{9}](https://tex.z-dn.net/?f=%5Cfrac%7B6-4x%7D%7B9%7D)
Answer:
1. Profit on stock transaction = 1400
2. percentage return on investment = 11.57
Step-by-step explanation:
stock's purchase price = 12,100
stock's selling price = 13,500
profit = stock's selling price - stock's purchase price
= 13,500 - 12,100
= 1,400
For, percentage return on investment;
⇒ percentage return = ![(\frac{profit}{purchase price })100](https://tex.z-dn.net/?f=%28%5Cfrac%7Bprofit%7D%7Bpurchase%20price%20%7D%29100)
= ![(\frac{1400}{12100})100](https://tex.z-dn.net/?f=%28%5Cfrac%7B1400%7D%7B12100%7D%29100)
= ![11.57](https://tex.z-dn.net/?f=11.57)
oh no no no no no no boi'
256 * 40 = 10,240 cm needed
so if the balls are 30 cm each then
10, 240 divided by 30 = 341.3
so the teacher will need 342 balls.
