PLEASE HELP ME!!!

Answer 1

Answer:

$350 * D \geq 1400$

$D\ge 4$

This means that the family must travel for at least 4 days.

Step-by-step explanation:

Given

$Rate = 350\ miles\ daily$

$Distance = 1400\ miles\ (atleast)$

Required

Determine and solve the inequality

The number of days is represented with D

So:

On any D number of days, the family would have covered a distance of 350 * D miles

If the total distance is at least 1400, then the inequality is:

$350 * D \geq 1400$

[The term "At least" is used to represent greater than or equal to]

$350 * D \geq 1400$

Divide through by 350

$\frac{350 * D}{350} \ge \frac{1400}{350}$

$D \ge \frac{1400}{350}$

$D\ge 4$

This means that the family must travel for at least 4 days.
