Answer:

Step-by-step explanation:

I am going with A......12x + 7y....x = # of adult and y = # of children.....adults cost 12 and children cost 7 <====

B doesn't make much sense....u could say x was for girls and y for boys...but u already know how many there are....so I am not sure what the x and y could stand for.

C does't make much sense either....x would have to be red marbles and y would have to be green marbles...but just like B, u already know how many there are....so not sure what x and y could stand for

D. wrong....because the box containing x 7 oz packages and y 12 oz packages.....12x + 7y....for this one to be correct, it would have to have x 12 oz packages and y 7 oz packages

Ede4ka [16]

First you multiply 145 by 01.75 to get how much you add to the total. You add 253.75 to 145 and get 398.75 as the answer

Is M a midpoint of line AB= ? AB= 27 and MB =14 A maybe B can’t be C no D yes

My name is Ann [436]

The answer is B/C.—M is in fact NOT a midpoint of line AB. This is because to be a midpoint the distance between both endpoints and the midpoint must me equal. If AB has equaled 28 then is would be, but in this case NO. To get AM you just need to do 27-14. AM would be 13 (if you need that too)
