Mary is buying tickets for a movie.
• Each adult ticket costs $9.
Each child ticket costs $5.
Mary spends $110 on tickets.
- Mary buys 14 total tickets.

adult 10

child 4

Step-by-step explanation:

for example,we buy x tickets for adults,y tickets for children.

so we can know x+y=14,9x+5y=110

5(x+y)=70

110-70=40

40/(9-5)=10,this is for adults

the rest are for child

9×10=90+15=105+5=110

Step-by-step explanation:

english, cause i can’t you

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
