Brainliest so that I can level up!
Step-by-step explanation:
7/10=r-(-8/5)
7/10=r+8/5
7/10 - 8/5= r + 8/5 - 8/5
7/10 - 8/5 = r
7/10 - 16/10 = r
-9/10 =r
r= - 0.9
Answer:
-9/10 =r
Step-by-step explanation:
7/10=r-(-8/5)
Subtracting a negative is like adding
7/10=r+(8/5)
Subtract 8/5 from each side
7/10 - 8/5=r+(8/5) - 8/5
7/10 - 8/5 = r
Get a common denominator
7/10 - 16/10 = r
-9/10 =r
