13=-4k+9
Whats k?
Pl help me due today

Explanation:

13 = -4k + 9

Flip the equation

−4k + 9 = 13

Subtract 9 from both sides

−4k + 9 − 9 = 13 − 9

−4k = 4

Divide both sides by -4

−4k / -4 = 4 / -4

Simplify

k = -1

k=-1

Step-by-step explanation:

13=-4k+9

switch sides

-4k+9=13

subtract 9 from both sides

-4k+9-9=13-9

simplify

-4k=4

divide both sides by negative 4

-4k/-4=4/-4

simplify

k=-1

hope this helps :) have a nice day !!

the answer is b.)

< 1=< 2

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
