Answer: x = 0

Step-by-step explanation:

Given:

x + 4x = 0

Combine like terms:

5x = 0

Divide both sides of the equation by 5:

x = 0

We can also check our work by graphing. See attached, intercepts of the x-axis are solutions.

10m3 of air weigh 13 kg. Chapter Reference c How much does the air weigh in a room 4.2m long, 3.5m wide, and 2.6m high?

Zarrin [17]

Answer:

The air weight in a room is 49.69 kg.

Step-by-step explanation:

It is given that the room is 4.2m long, 3.5m wide, and 2.6m high. It is also given that 10 m³ of air weigh 13 kg.

The formula to find the volume of cuboid is,

$V=l\times b\times h$

$V=4.2\times 3.5\times 2.6$

$V=38.22$

The volume of room is 38.22 m³.

Since it is given that, 10 m³ of air weigh 13 kg. So,

$1 m^3=\frac{13}{10}kg$

$1 m^3=1.3kg$

So the air weight in the room is,

$\text{Air weight}=1.3\times 38.22$

$\text{Air weight}=49.686\approx 49.69$

Therefore the air weight in a room is 49.69 kg.

Mice21 [21]

Call Canada's population $c$ , and call the U.S. population $u$ .

We see that $c=\frac{u}{10}$ . Substituting 32 million for c, we see that $32,000,000=\frac{u}{10}$ . Multiplying by ten, we see that $320,000,000=u$ . By using Algebra properly, we have ensured that the number of zeroes in our final answer is correct.
