Mathematics
1 answer:
sveticcg [70]2 years ago
5 0

Answer:

x=0.9

Step-by-step explanation:

1. You first have to isolate the x term so you subtract 6.814 from both sides which makes the equation 1.54x=1.386

2. Then, to isolate "x", you divide 1.54 on both sides to get rid of the 1.54 which makes x=.9

20. A frock is marked Rs. 228 at a discount of 20% is given on it. What is the discount and
Darina [25.2K]

Answer and step-by-step explanation:

20. Because the discount is 20% of the given price so the discount would be"

228/100*20

= 45.6 Rs

Its selling price would be:

228 + 45.6 = 273.6 Rs

21. Sales tax would be:

450/100*5

= 22.5 Rs

Total price in bill = 22.5 + 450 = 472.5 Rs

22. 10% tax of 3300 would be:

3300/100*10 = 330 Rs

Price before tax = 3300 - 330 = 2970 Rs

23. He spent in total of:

2500 + 500 = 3000Rs

He sold for 3300 Rs

He gain 3300 - 3000 = 300 Rs profit

His loss gain percent = 3300/3000 * 100 = 110%

24. On the first bike, he earn:

2500/100*20 = 500 Rs

On the second bike, he lose:

2500/100*25 = 625 Rs

He lose in total of 625 -500 = 125 Rs

his loss percentage = (2500+500) + (2500 - 625) / 5000* 100

= 100% - (2500+500) + (2500 - 625) / 5000* 100

= 100% - 97.5%

He lose 2.5% money

Hope this helped :3

Need help step by step​

Y = mx + b

8x - 4y - 9 = 0

first you move the nine to the other side of the equal sign (add nine to both sides)

8x - 4y = 9

then you need to also move your 8x over to the other side as well (remember we are trying to get y by itself!)

- 4y = -8x + 9

then we are going to divide -4 to both sides

and you get

y = 2x - 9/4

we can then identify the slope as 2

so B. 2 would be your answer

hope this helped
