Which calculations performed on the calculator are reasonable, using estimation? Check all that apply.
2.8 x 210 = 588
50= -5
D 89 0.18 = 160.2
03 -0.04
- x 5 = 3.75

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

using pemdas, (order of operations) you'll see the answer is 24.
