given this equation: 2x + 6 = 3x + 4 (a) write a real-word proble that can be represented by the given equation. explain what your variable represents.

x=2

Step-by-step explanation:

1.Subtract 6 from both sides of the equation

2.Simplify

3.

Subtract

3x

from both sides of the equation

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.

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°
