Ethan ordered 4 sub sandwiches for a party. each 1/2 sandwich is one serving. does he have enough to serve 7 friends? how much is leftover or how much more is needed. explain

He has enough bc if he has 7 friends and 4 subs and u multiply 4 times 2 bc there cut in half he's gonna have 8 pieces 7 for the friends and 1 for him

If half of each sub is 1 serving, and he has 4 whole subs, then he would have 8 servings so he would be able to feed 7 friends and himself. I don't know if the final product is including him or not so if it is. then there are no subs left over, if it is not, then there is only 1/2 sub left

Thank You!

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

0 = ( 2 - 4 ) ( p + q )0 = ( 2 - 4 ) ( 2 + 5 i ),   by multiplying these0 = ( 4 + 10 i - 8 - 20 i )0 = 4 - 8 + 10 i - 20 i0 = - 4 -10 i   0 = 2 ( - 2 - 5 i )0 / 2 = - 2 - 5 i- 2 - 5 i = 0- 5 i = 2i = 2 / - 5

Cwill be your correct answer
