Lin wants to empty the hot tub to clean it. She has a 300 gallon hot tub and empties it at a rate of 20 gallons each minute. Write it!: Write a sentence about ONE of the points you plot on your graph and what it means in context to Lin.

Create the Equation: Write an equation based on Lin's hot tub.

Read the graph: How many gallons will be in the tub after 8 minutes?

your answer would be 10x - 1

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

~

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
