If lydia wants to text at least 8 characters per second, like james, then the equation 10r + 4 = 8 could be used to model this situation. solve this equation for r.

r = 2/5

Step-by-step explanation:

Hi, to answer this question we have to solve the equation given for r:

10r + 4 = 8

Subtracting 4 from both sides

10r+4-4=8-4

10r = 4

Dividing each side by 10:

10r/10 =4/10

r = 2/5

In conclusion, the value of r is 2/5 (or 0.4 in decimals)
