Two classes have a total of 50 students. One of the classes has 6 more students than the other. How many students are in the larger class.

Answers

Let's say 'x' to number of the students in the smaller class. Since the larger one is 6 more than the smaller one, its number would be 'x+6'. So their sum is equal to

$x+x+6=2x+6$ and we know total is 50 so:
$2x+6=50\n 2x=50-6\n 2x=44\n x=\frac { 44 }{ 2 } \n x=22$

x is 22 so the larger number 'x+6' is equal to : $x+6=22+6=28$

There are 28 students in the larger class.

Let's assume the number of students in one class is x.

Since the other class has 6 more students, the number of students in the other class is x + 6.

The total number of students in both classes is 50.

Therefore, we can write the equation:

x + (x + 6) = 50

2x + 6 = 50

Subtracting 6 from both sides:

2x = 44

Dividing both sides by 2:

x = 22

So, the number of students in the larger class, which is x + 6, is:

22 + 6 = 28

Therefore, there are 28 students in the larger class.

Answers

Hello,

$\frac{d^2( \int\limits^x_0 { (2)/(t^2+3t+1) } \, dt )}{dx^2} = (d((2)/(x^2+3x+1)) )/(dx) \n = (-2(2x+3))/((x^2+3x+1)^2)$

A toddler crawled 3 yards, stopped, then continued to crawl 11 more feet. How many feet did he travel in total?

Answers

So how many Feet right? A yard has 3 feet in it so 3*3=9, nine feet there. So 9+11= 20. The toddler traveled 20 feet total.

add them up
wait, convert yards to feet
3 feet in 1 yard
times 3
9 feet in 3 yard

9 feet first, then 11 feet
add
9+11=20 feet
