Answer:
25%
Step-by-step explanation:
percent change = (new number - old number)/(old number) * 100%
Here, new number = 30, and old number = 24.
percent change = (30 - 24)/(24) * 100%
percent change = 6/24 * 100%
percent change = 0.25 * 100%
percent change = 25%
Answer:
c = 
f= 1500
Step-by-step explanation:
Tenemos la siguiente ecuación
Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones

Si restamos la segunda ecuación de la primera, tenemos que

Luego

Entonces 
Si tomamos la primera ecuación, tenemos que
. Es decir,

Esta solución, al plantear 2 ecuaciones y dos incógnitas, plantea un sistema dos por dos.
Answer:
it's literally 10 just divide
Step-by-step explanation:
Write the prime factorization of each term:
9r⁵s = 3² × r⁵ × s
6r⁴s² = 2 × 3 × r⁴ × s²
12r²s = 2² × 3 × r² × s
The greatest common factor will have all the common factors raised to their lowest exponent.
So all three terms have 3, r, and s as factors. The lowest exponent of 3 is 1. The lowest exponent of r is 2. The lowest exponent of s is 1.
GCF = 3 × r² × s
GCF = 3r²s
Factor out the GCF:
9r⁵s + 6r⁴s² − 12r²s
3r²s (3r³ + 2r²s − 4)
