Answer:
0.3
Step-by-step explanation:
(7.4-1.1) - (2.1-8.1)
Lets start with (7.4-1.1)
Step 1:
(7.4-1.1) =6.3 (All you do is subtract 7.4-1.1 and it gives you 6.3)
Step 2: Lets do (2.1-8.1)
(2.1-8.1)= -6 (2.1 minus 8.1 gives you -6 because 2.1 is smaller than 8.1 so it will give you a negative)
Step 3: Subtract
6.3-6
So your answer would be 0.3

Hello!
Let's begin by multiplying all 3 terms by 4, to remove the fraction:
2(r-3) - 8(4) = 50(4)
Then 2r - 6 - 32 = 200. Consolidating the constants on the right side, we get:
2r = 162. Solving for r, we divide both sides by 2, obtaining r = 81 (answer)
