An earthworm travels 27 cm in 9 min. Calculate the earthworm's speed in cm/min and in meters/sec.

The answer is 3 cm per minute & 0.05 m per second.

Explanation:

The inequality equation is

(2,764 + x) ≥ 5,000

Solving further, we obtain

x ≥ 2,236

where x is the amount of money the Li's family still need to save.

Step-by-step explanation:

Li’s family is saving money for their summer vacation. Their vacation savings account currently has a balance of $2,764. The family would like to have at least $5,000.

Which inequality can be used to determine the amount of money the family still needs to save?

Solution

Let x represent the amount of money the Li's family still need to save.

It is given that the family already have $2,764 in their savings account and the family needs at least $5,000.

The total amount the family will have in total, after saving x dollars to join the already saved $2,764 will now be

$(2,764 + x)

This amount must be at least $5,000, that is, this amount must be greater than or equal to $5,000.

So, the inequality equation is then

(2,764 + x) ≥ 5,000

Solving further by subtracting 2,764 from both sides, we obtain

x ≥ 2,236

Hope this Helps!!!
