In an ecosystem some animals get energy by eating plants an leek can eat 20 pounds of plants each day write and evaluate an expression to find how many pounds of plants a herd of 18 elk can eat in one week.

2520 pounds can be eaten by a herd of 18 elk in one week.

Step-by-step explanation:

Given: A elk an eat 20 pounds of plants in one day .

Now , Quantity of plants eaten by a herd of elk  = (Quantity of plants eaten per day) x (Number of elks ) x (Number of days)

So, the quantity of plants a herd of 18 elk can eat in one week = 20 x 18 x 7   [1 week = 7 days]

= 2520 pounds

Hence, 2520 pounds can be eaten by a herd of 18 elk in one week.

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
