Shau-uen solved the equation 18.5 w + 6.5 w minus 2.8 w = 149.1. Her work is shown below. Step 1 18.5 w + 6.5 w minus 2.8 w = 149.10 Step 2 25 w minus 2.8 w = 149.1 Step 3 Negative 2.8 w = 5.964 Step 4 w = negative 2.13 In which step did Shau-uen make her first error?

i hope this is what you were looking for.

see attached graph

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200
