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

Lynna [10]

Answer:

$smaller \: x = \boxed { - 5} \\ larger \: x = \boxed 2$

Step-by-step explanation:

$5 {x}^{2} + 15x - 50 = 0 \\ 5( {x}^{2} + 3x - 10) = 0 \\ {x}^{2} + 3x - 10 = 0 \\ {x}^{2} + 5x - 2x - 10 = 0 \\ x(x + 5) - 2(x + 5) = 0 \\ (x + 5)(x - 2) = 0 \\ x + 5 = 0 \: or \: x - 2 = 0 \\ x = - 5 \:or \: x = 2 \\ smaller \: x = \boxed { - 5} \\ larger \: x = \boxed 2$
