Emma Bought 17 packets of rolls for a party there were 18 rolls in a packet after the party there were 8 rolls left how many rolls were eaten

298 rolls were eaten

Step-by-step explanation:

we are given that Emma bought 17 packets and that in each packet, there were 18 rolls.

Hence, Emma bought,

17 packets

= 17 packets x 18 rolls per packet

= 306 rolls

We are further given that there were 8 rolls left over.

We know that,

total number of rolls in the beginning - number of rolls eaten = rolls left over.

If we substitute the known values into this expression, we will get

306 - number of rolls eaten = 8

number of rolls eaten = 306 - 8

number of rolls eaten = 298

there is no grid

step-by-step explanation:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
