Question

9r-8,67r=0,6699 плиииииииииз

Answer 1

1) 9r-8,67r=0,6699
0.33r=0,6699
r=0,6699:0,33
r=2,03.

Answer 2

To solve the equation 9r - 8.67r = 0.6699, we can combine like terms and isolate the variable r. Let's go step by step:

9r - 8.67r = 0.6699

First, subtract 8.67r from both sides of the equation:

9r - 8.67r - 8.67r = 0.6699 - 8.67r

Simplifying the left side:

(9 - 8.67)r = 0.6699

Subtracting 8.67 from 9:

0.33r = 0.6699

Next, divide both sides of the equation by 0.33 to solve for r:

(0.33r) / 0.33 = 0.6699 / 0.33

Simplifying:

r = 2.03

Therefore, the value of r that satisfies the equation 9r - 8.67r = 0.6699 is r = 2.03.
