2.8 = (12*9.8 - 8/3 V²) ÷ 12 find V

5.6

Step-by-step explanation:2.8×12=12×9.8-8/3v^2

33.6=117.6-8/3v^2

8/3v^2=117.6-33.6

8/3v^2=84

8v^2=84×3

8v^2=252

V^2=31.5

V=√31.5

V=5.6125

V~5.6

found it xd it ok yt

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
