3x+ 2y= 4 solving for x

Mathematics
2 answers:
Jet001 [13]2 years ago
4 0

First step: Isolate the term that has x. To do that, subtract 2y from both sides.

3x + 2y = 4

3x = -2y + 4

Now divide both sides by 3.

x = \dfrac{-2y + 4}{3}

First you subtract 2y and now you have 3x=-2y+4 then you decide my 3 and now your answer is x= -2/3+4/3 that’s your answer

Lúcia is using energy at a rate of 420 kilocalories (kcal) per hour (h) ice skating.
kakasveta [241]

Answer:

7000 cal/min

Step-by-step explanation:

It is mentioned that, Lucia is using energy at a rate of 420 kilo calories per hour ice skating

We know that,

1 kilo calories = 1000 calories

Using unitary method :

420 kilo calories = 420,000 calories

Also,

1 hour = 60 minutes

In this case, Lucia is using energy per 60 minutes =  420,000 calories. So,energy used by her per minute is :

E=\frac{420000}{60} =7000 calories

Hence, Lucia is using 7000 calories per minute.
