Step-by-step explanation:
Sean , los precios del saco de arroz y el saco de azúcar, respectivamente. A continuación, traducimos cada oración relevante en ecuaciones matemáticas:
(i) <em>El precio del saco de arroz es a 2 como el precio del saco de azúcar es a 3</em>:
Aquí se menciona una igualdad entre expresiones racionales, es decir:
(1)
(ii) <em>El producto de ambos precios es numéricamente 3456</em>:
(2)
Ahora resolvemos el sistema de ecuaciones, despejamos en (1):
Y la aplicamos en (2):
El precio del saco del azúcar es de 72.
Answer:
(-7,10)
please see the attached picture for full solution..
hope it helps..
Good luck on your assignment
Module 4, students extend what they already know about unit rates and proportional relationships to linear equations and their graphs. Students understand the connections between proportional relationships, lines, and linear equations in this module. Students learn to apply the skills they acquired in Grades 6 and 7, with respect to symbolic notation and properties of equality to transcribe and solve equations in one variable and then in two variables.
The student materials consist of the student pages for each lesson in Module 4.
The copy ready materials are a collection of the module assessments, lesson exit tickets and fluency exercises from the teacher materials.
the top is equal to the bottom so u take the top and add it with it's self 24 +24 and do the same with the sides 9+9 add them together to get 66
Answer:
LHS.= Sin 2x /( 1 + cos2x )
We have , sin 2x = 2 sinx•cosx
And. cos2x = 2cos^2 x - 1
i.e . 1+ cosx 2x = 2cos^2x
Putting the above results in the LHSwe get,
Sin2x/ ( 1+ cos2x ) =2 sinx•cosx/2cos^2x
=sinx / cosx
= Tanx
.•. sin2x/(1 + cos2x)= tanx
