Answer:
x = -3 or x = 5
Step-by-step explanation:
Solve: x^2 -2x = 15
x^2 - 2x - 15 = 0
Use the Diamond method of factoring
-15 = 3* -5 and 3 - 5 = -2 so...
x^2 - 2x - 15 = x^2 - 5x + 3x - 15
x^2 - 2x - 15 = x *(x - 5) + 3*(x - 5)
x^2 - 2x - 15 = (x + 3)*(x - 5)
x^2 - 2x - 15 = (x + 3)*(x - 5) = 0
solve (x + 3 ) = 0 and (x - 5) = 0
x = -3 or x = 5
Answer:
Step-by-step explanation:
Amount of money to invest in Atlantic Oil= A
Amount of money to invest in Pacific Oil = P
Total money invested in the two oil companies = A+P
Since at least 60% of the money invested in the two oil companies must be in Pacific Oil
Hence the required model is

Answer: ella usó (1/2) kg de arroz para cocinar.
Step-by-step explanation:
La madre de Ernesto tenía una bolsa con 3/4 kg de arroz.
Sabemos que uso 2/3 de esa cantidad para hacer un guiso.
Entonces ella usó 2/3 de 3/4 kilogramos de arroz.
Entonces ella usó:
(2/3)*(3/4) kg de arroz.
Recordemos que esto se puede escribir como el producto entre los numeradores dividido por el producto de los denominadores:
(2*3)/(3*4) kg de arroz.
(6/12) kg de arroz
(1/2) kg de arroz.
Esto significa que ella usó (1/2) kg de arroz para cocinar.
