Simplify 8(3 - 2x).

a.24x - 16
b.16x - 24
c.24 - 16x

24x-16x c

Step-by-step explanation:

8(3-2x)

8*3=24

-2x*8=-16x

24x-16x

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

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°
