Answer:

She has 27 students now.

Step-by-step explanation:

Given :

The teacher has 30 students

10% students left.

To find : how much students does she have now?

Solution :

Since we are given that teacher has 30 students .

And 10% of students left

⇒ 10% of 30


⇒\frac{10}{100} *30


⇒\frac{300}{100}


⇒3


Thus, 3 students left .

She had 30 students . three students left.

So, now she have 30 - 3 = 27 students .

Hence she has 27 students now.

H+3h+4h=100 how do i get h?
Dominik [7]

Answer:

h = 12.5

Step-by-step explanation:

Simplifying

h + 3h + 4h = 100

Combine like terms: h + 3h = 4h

4h + 4h = 100

Combine like terms: 4h + 4h = 8h

8h = 100

Solving

8h = 100

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Divide each side by '8'.

h = 12.5

Simplifying

h = 12.5
