Write a real world situation that can be represented by the expression x - 12 subtraction

Let's say that 12 pictures were stolen from an art gallery.

Let x = number of pictures originally in the art gallery

The expression x - 12 in this situation means

that we take away 12 from our variable.

So 12 pictures stolen from the art gallery represents the expression x - 12.

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
