7-3y=34
What's y??
Plzzz help due today!!

y = -9 (negative 9)

Step-by-step explanation:

7 - 3(-9) =

7 - (-27) =

34

Hope this helped and pls mark brainliest!

Explanation:

7 - 3y = 34

Simplify both sides of the equation

7 − 3y = 34

7 + −3y = 34

−3y + 7 = 34

Subtract 7 from both sides

−3y + 7 − 7 = 34 − 7

−3y = 27

Divide both sides by -3

−3y / -3 = 27 / -3

Simplify

y = -9

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
