4x+1=9+4y please help me solve for x please show step by step I’m very confused

Inessa05 [86]

Answer:

Step-by-step explanation:

First of all, you would combine like terms, giving you 4x - 4y + 1 = 9.

Next, subtract the numbers, which gives you 4x - 4y = 8.

Finally, divide both sides by 4, which will come to the conclusion of x - y = 2, the simplest form of which this equation can be broken down to.

The ratio of hydrogen to oxygen atoms in water molecules is 2 to 1. If the beaker of water contained 4.1 moles of oxygen atoms,

Ad libitum [116K]

Answer:

8.2

Step-by-step explanation:

We have been given that the ratio of hydrogen to oxygen atoms in water molecules is 2 to 1.

We can represent this information as: $\frac{\text{Hydrogen}}{\text{Oxygen}} =\frac{2}{1}$

Let x be amount of moles of hydrogen atoms in water beaker. The proportion of hydrogen and oxygen moles will be same in water beaker.

Upon substituting our values in above proportion we will get,

$\frac{2}{1} =\frac{x}{4.1}$

$x=2\times 4.1$

$x=8.2$

Therefore, the moles of hydrogen atoms in water beaker will be 8.2.
