Answer:
1240 students.
Step-by-step explanation:
There are 558 girls and 682 boys
First take the square root of 25, then take the square root of 49.
It is as easy as separating the square root to apply to both terms separately instead of combined.
sqrt(25)/sqrt(49)
5/7
Answer:
The answer is 1920, right? Here is how-
The numbers must contain at least three digit and can go above that which means the answer has 3 4 5 and 6 digits all together.
For three digits , there will be 6*5*4 = 120
For 4 Digits, There will be 6*5*4*3=360 possible numbers
For 5 digits , there will be 6*5*4*3*2 = 6! = 720
For 6 digits, there will be 6*5*4*3*2*1 = 6! = 720
<Note- the digits are non repeating as the question said it to be “different digits” >
Now add them up = 120+360+2*720 = 1920
Step-by-step explanation:
J = jeans
T = t-shirts
You: 5j + 10t = 140
Friend: 3j + 5t = 79
To use elimination in this problem, multiply the second equation by -2 so that 10t and 5t can cancel out:
5j + 10t = 140
-6j - 10t = -158
We are left with -j = -18 or j = 18
Substitute 18 into any equation. I'll use the first equation:
5(18) + 10t = 140
90 + 10t = 140
10t = 50
t = 5
