Mathematics
1 answer:
jenyasd209 [6]3 years ago

Answer:

x = - 3

y = - 2

Step-by-step explanation:

Start with the second equation. Switch

3y = 2x               Divide by 3

3y/3 = 2x/3

y = 2x/3

Now go to the first equation. Put the value for y in the first equation.

x - 3(2x/3) = 3      Cancel the 3s on the left.

x - 2x = 3              Combine

-x = 3                    Multiply by -1

-1(-x) = 3(-1)

x = - 3

Now go back to the original equation I have called the second equation

2x = 3y

2(-3) = 3y                  Put in - 3 for x

- 6 = 3y                     Divide by 3

-6 / 3 = y

y = - 2

Hm
melomori [17]

Answer:

108m

Step-by-step explanation:

Hello, to find the height of the bigger triangle, you take the width of the bigger triangle and divide by the width of the smaller triangle like this:

72/0.8=90

Then, you take 90 and you multiply it by the height of the smaller triangle like this:

1.2 x 90= 108

So the height of the bigger triangle is 108m.

A gas at standard temperature and pressure was measured as having a mass of 1485 grams (g) in a volume of 750 liters (L). Which
tangare [24]

Answer:

Here we will use the relation:

Density = mass/volume.

We know that:

Mass = 1485g

Volume = 750L

Density = 1485g/750L = 1.98 g/L

We do not have the options in order to select the correct one, but knowing this density, we can suppose the possible gases.

Two "common" gases with densities similar to this one are:

Carbon Dioxide, with d = 1.977 g/L

Dinitrogen Monoxide, with d = 1.977 g/L

In both cases, if we round up we will get the same density that we calculated at the beginning, so either of these can be the correct option.
