Question

1. (06.02 mc)

the time hazel spends commuting to work can be represented by two expressions:
time to work: ( x + 6y )
time from work: ( 3x - 10y )
which expression represents the total time hazel spends commuting to and from work each day? (1 point)
( 7x - 7y )
( 4x - 4y )
( 4x + 4y )
( 4x - 16y )

Explanation:

Step1: Add the two commute times

$(x + 6y) + (3x - 10y)$

Step2: Combine like x terms

$x + 3x + 6y - 10y = 4x + 6y - 10y$

Step3: Combine like y terms

$4x + (6y - 10y) = 4x - 4y$

Answer:

B. $4x - 4y$
