Question

Pllllllsssssss help quick and accurately

Answer 1

Answer:

$r=\frac{-9}{10}$

Step-by-step explanation:

$\frac{7}{8}=r-(\frac{-8}{5})$

opening bracket will change the sign

$\frac{7}{10}=r+\frac{8}{5}$

in oreder to find the value of subtract $\frac{8}{5}$  on both sides

$\frac{7}{10} - \frac{8}{5}$=r

taking LCM

$\frac{7}{10}-\frac{8*2}{5*2}$=r

$\frac{7}{10}-\frac{16}{10}=r$

$\frac{-9}{10}=r$

i hope it will help you :)

Answer 2

Answer:

r = $\frac{-9}{10}$

Step-by-step explanation:

Step 1: Convert symbols

7/10 = r + 8/5

Step 2: Subtract 8/5 on both sides

r = 7/10 - 8/5

Step 3: Combine like terms

r = -9/10

And we have our final answer!
