Dr. Zinnert is studying coastal plant ecology using remote sensing data. Satalite images enable her to deduce land coverage on coastal barrier islands on the coast of Virginia. Given the table below, what percent of barrier island is bare earth?

Report your answer to two decimal places and carry out all calculations in a single step using Excel to prevent accruing rounding error.

Ground Cover km2
Trees 1.4
Shrubs 2.3
Grass 1.4
Bare Earth 4.5

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
