Answer:

24 total students

Step-by-step explanation:

multiply 25 times 18 to get 450 then divide 450 by 75 then you get 6, which is the total amount of girls, so 6 + 18 = 24

x = number of students

75% of x = number of boys

(75/100)*x = 18

0.75x = 18

x = 18/0.75 <--- divide both sides by 0.75 to isolate x

x = 24

So there are 24 students in the class

Note how 18/24 = 3/4 = 0.75 = 75% represents the percentage of boys

Hint: Use decimal concept.

We know that, 1 rupee = 100 paise. We can reframe these questions as follows:

18 rupees 9 paise from 75 rupees 80 paise

18 rupees 9 paise can be represented as 18.09 rupees and 75 rupees 80 paise can be represented as 75.80 rupees. Now, on subtracting we’ll get,

75.80−18.09−−−−−− 57.71

Which means 57 rupees 71 paise

49 rupees 79 paise from 123 rupees 68 paise

49 rupees 79 paise can be represented as 49.79 rupees and 123 rupees 68 paise can be represented as 123.68 rupees. Now, on subtracting we’ll get,

123.68 −49.79−−−−−− 73.89

Which means 73 rupees 89 paise.

Note: We can also perform the subtraction by making all units the same that are paise and then subtract.

What is the slope of 5x-y =2
hodyreva [135]

Answer:

5

Step-by-step explanation:

To find the slope, rearrange the terms of this equation to y=mx+b form, where m is the slope.

Original equation: 5x-y=2

Subtract 5x to both sides: -y = -5x+2

Multiply both sides by -1: y = 5x-2\

This gives us the slope, which is equal to 5.

Let me know if this helps!
