I need some help please help me!

1. A

2. C

3. B

4. B

Step-by-step explanation:

1. Subtract 4.2 on both sides of the equation so you're left with y = -0.8

2. Add 1.9 on both sides of the equation so you are left with m = 4.

3. Distribute 1/5 into (3+2z) to get 3/5 + 2/5z - 4z = -3. Combine like terms so you have 3/5 - 3 3/5z = -3. Subtract 3/5 on both sides to get -3 3/5z = -3 3/5. Divide by -3 3/5 on both sides to get z = -1.

4. Distribute 4 into (2+ t) to get 1/2t -8 -4t = 20. Combine like terms to get -3 1/2t - 8 = 20. Add 8 on both sides to get -3 1/2t = 28. Divide -3 1/2 on both sides to get t = -8.

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

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°
