the national honor society is selling tickets for the spring dance. tickets are $12 for couples and $8 for singles. let x be the number of couples and y be the
number of singles. this system of equations represents the situation in which ticket sales totaled $1,580 and a total of 250 students attended the dance.
12x + 8y = 1,580
2x + y = 250
how many singles tickets were sold?
a)15
b)40
c)105
d)133

40 single tickets were sold.

Step-by-step explanation:

12x+8y=1580

2x+y=250

y=250-2x

12x+8(250-2x)=1580

12x+2000-16x=1580

-4x+2000=1580

-4x=1580-2000

-4x=-420

4x=420

x=420/4=105

y=250-2(105)=250-210=40

just find the gcf and solve the gcf's until you get each answer i have a really good feeling somethings missing xd (like the dimensions of the fence) *cough *cough *hint *hint

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
