Answer:

38 sq ft

Step-by-step explanation:

Add together the two triangles plus the rectangle area.

A(triangle1) = 1/2 bh = 1/2 4*4 = 8 sq ft

A(triangle2) = 1/2 bh = 1/2 4*3 = 6 sq ft

A(rectangle) = lw = 8*3 = 24 sq ft

A(total) = 8 + 6 + 24 = 38 sq ft

At the movie theatre, child admission is $5.40 and adult admission is $9.20 . on thursday, twice as many adult tickets as child
Scorpion4ik [409]
33 child tickets were sold that day.

adult tickets = a
child tickets = c

9.2a + 5.4c = 785.4
a = 2c

Substitute a into the first equation
9.2(2c) + 5.4c = 785.4
Simplify
18.4c + 5.4c = 785.4
Combine like terms by adding
23.8c = 785.4
Divide both sides by 23.8 to isolate the variable c
c = 33
