The model represents an equation. What value of x makes the equation true?
ch4aika [34]

Let's build the equation counting how many x's and 1's are there on each side.

On the left hand side we have 5x's and 8 1's, for a total of 5x+8

On the left hand side we have 3x's and 10 1's, for a total of 3x+10

So, the equation we want to solve is

5x+8 = 3x+10

Subtract 3x from both sides:

2x+8 = 10

Subtract 8 from both sides:

2x=2

Divide both sides by 2:

x=1

0,00000826 * 235 × 10 ^ -7 / 0,0017 × 10 ^ -2

También;

8.26 * 10 ^ -6 * 2.35 * 10 ^ -5 / 1.7 * 10 ^ -5

= 19,411 * 10 ^ -11 / 1,7 * 10 ^ -5

= 1,42 * 10 ^ -5
