Solve the system of equations using the elimination method. 1. 3 − 2 = 10 7 + 2 = 30 pls hurry

1 = 72 = 30

Step-by-step explanation:

I think that is answer but im not sure if the 10 is being multipilied by the 7.

1. 10 times 7 = 70 + 2 = 72

2. 3-2 =1

3. 1 = 72 = 30

50x5=$250

step-by-step explanation:

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°
