<span>Multiplying with 6 is a mathematical process similar to multiplying with 3, in that setting up the greatest common factors between the two is easy due to the fact that 6 is a multiple of 3. As 6 is simply 3 doubled, any multiple of 6 will be the relative multiplation for 3 doubled. </span>
Write it in the form of y2-y1

x2-x1
I'm pretty sure as the workers elevates to the top, the angles grow bigger (obtuse). As they descend, the angles become smaller (acute). Not very positive on the terms, ahah.
Answer:
8 ejercicios
Step-by-step explanation:
De acuerdo a la información dada, puedes plantear las siguientes ecuaciones:
x+y= 45 (1)
7x-1y= 19 (2)
x= ejercicios que resolvió bien
y= ejercicios que resolvió mal
Primero, puedes despejar x en (1):
x= 45-y (3)
Segundo, debes reemplazar (3) en (2):
7(45-y)-1y=19
315-7y-1y= 19
315-8y= 19
315-19= 8y
296= 8y
y= 296/8
y= 37
Tercero, debes reemplazar el valor de y en (3) para encontrar x:
x= 45-37
x= 8
De acuerdo a esto, la respuesta es que el hijo ha resuelto bien 8 ejercicios.
K = 5 because according to cross multipication, which is what you need to do to get an answer for these kinds of questions, you have to times 6 by 15 then divide that answer by 18 and you have your answer: 5 (6 x 15 = 90 90 / 18 = 5)
