Responder:
2 1/4 kilogramos
Explicación paso a paso:
Si Juan compró 1/2 kg de azúcar, 3/4 kg de harina y 1 kg de huevo en el supermercado, y lo coloca en una bolsa, para saber el peso de la bolsa, sacaremos la suma de las masas de los ingredientes.
Peso de la bolsa = 1 / 2kg + 3 / 4kg + 1kg
Encuentra el LCM
= 1/2 + 3/4 + 1/1
= (2 + 3 + 4) / 4
= 9/4
= 2 1/4 kg
Por tanto, la bolsa pesará 2 1/4 kg.
To be honest I don't know❤️
Using the defects method, which relationship represents the Law of Cosines if the measure of the included angle between the sides a and b of ΔABC is less <span>than 90°?

I'm really not familiar with this subject area but I have encountered this problem before and this answer was confirmed.
Answer:
y = 2x - 25
Step-by-step explanation:
First find the gradient, we can see it goes through (30,35) and 35,45), and since gradient is found by 'change in y / change in x' we can do: (45-35) / (35-30) = 10/5 = 2
So we know we are looking for an equation with 2x in it.
We have two options: y = 2x - 25 and y = 2x - 75.
Plug in one of the points and see which of the equations works.
Replacing y with 35 and x with 30 in the first equation we have: 35 = 2(30) - 25 = 60 - 25 = 35, this is indeed true.
However if we did the same with the second equation: 35 = 2(30)-75 = 60 - 75 = -15, this is false since 35 does not equal -15, so it can't be the second equation.
In conclusion it must be y = 2x - 25
