vova2212 [387]

Answer:

x≥2

Step-by-step explanation:

Let's solve your inequality step-by-step.

12−7x≤−2

Step 1: Simplify both sides of the inequality.

−7x+12≤−2

Step 2: Subtract 12 from both sides.

−7x+12−12≤−2−12

−7x≤−14

Step 3: Divide both sides by -7.

−7x/−7 ≤ −14/−7

x≥2

3. Convert 150 yards per minute to feet per day.
vesna_86 [32]

One day has 24 hours.

One hour has 60 minutes.

One day has 24 x 60 = 1440 minutes.

1 yard is 3 feet.

150 yards x 3 = 450 feet.

150 yards per minute = 450 feet per minute.

450 x 1440 = 648,000 feet per day.
