A theater is tracking the number of adults and children in the audience at various shows. The table shows how the number of adults and children are related.
Adults
(x)
Children
(Y)
Select the equation that matches the relationship.

x+y=1000
y - 1000
y=1000
y=1000x

500 500
450 550
400 600
350 650

x + y = 1000

Step-by-step explanation:

From the. Table provided :

500 500

450 550

400 600

350 650

X = number of children

Y = Number of Adult

The sum of both x and y gives 1000 in all 4 scenarios :.

500 + 500 = 1000

450 + 550 = 1000

400 + 600 = 1000

350 + 650 = 1000

Hence, equation ;

x + y = 1000

b

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
