3 0

Answer:

No its not

Step-by-step explanation:

When 42(x + 14y) is simplified:

42(x + 14y)

Expand and remove the brackets. Remember brackets mean to multiply.

42*x

42x

42*14y

588y

42x+588y

Therefore 42x-56 is NOT EQUIVALENT to 42(x + 14y) but is equivalent to 42+588y

Marissa and haylie met for dinner in downtown Savannah. Marissa did flat-rate valet parking for $20. Haylie went to another vale
shtirl [24]

Answer:

6 hours; each paying $20

Step-by-step explanation:

To start off, we know that Marissa paid exactly $20 for parking. Since we know that Marissa and Haylie paid the same amount, we must now move on to Haylie.

Haylie paid $5 upfront. Now we must figure out how many hours Haylie must have stayed if each hour costed $2.50. We can figure this out by dividing $15 by $2.50 since Haylie already paid $5 upfront.

$15 / $2.50 = 6

This means that Haylie and Marissa stayed for 6 hours and paid exactly $20 dollars each.
