Arestaurant needs to plan seating for a party of 150 people. large tables seat 10 people and small tables seat 6. let x represent the number of large tables and y represent the number of small tables. the expression 10a + 6b, which represents the total number of people you can seat using a large tables and b small tables, is called a linear combination. for instance, 150 people could be seated using 12 large tables and 5 small tables. use that expression to enter an equation in standard form that models all the different combinations of tables the restaurant could use. then identify at least one possible combination of tables other than (12, 5).

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
