All 3000 seats in a theater are being replaced. so far, 5 section of 236 seats and a sixth section containing 348 seats have been replaced. how many more seats do they still need to replace?

So, to find the number of seats already replaced:

5 x 236 = 1180

1 x 348 = 348

1190 + 348 = 1528

So 1528 seats have been replaced.

3000 - 1528 = 1472

And 1472 seats still need to be replaced.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
