Part A:

Answer:

336\leq 14m\leq 448

Step-by-step explanation:

Step 1:

Jodi bought a new car with a 14-gallon gas tank.

Around town, she can drive 336 miles on one tank of gas.

She drove 448 miles on one tank on a trip on the highway

<em>m</em> will represent the number of miles per gallon of gas.

Step 2:

If <em>m </em>represents the number of miles per gallon of gas she gets and her tank holds 14 gallons then 14<em>m</em> represents the number of miles she can drive.

14 gallons · \frac{m}{1} = 14m

Around town, she was able to drive 336 miles and on the highway, she was able to drive 448

So... 336\leq 14m\leq 48

Part B:

Answer:

The compound inequality is two simple inequalities separated by "and" is 336\leq 14m and 14m < 448.

Step-by-step explanation:

Step 1:

We are told Jodi bought a new car with a 14-gallon gas tank.

Around town, she can drive 336 miles on one tank of gas. She drove 448 miles on one tank of gas on her first trip traveling on highways

Here we need to rewrite the compound inequality

Let m represent the number of miles per gallon of gas.

Step 2:

Since 14m must greater than or equal to 336 and less than or equal to 448:

The two simple inequalities must be separated by the word "and"

336\leq 14m and 14m

Part C:

Answer:

The solution of simple inequality is 24\leq m and m\leq 32

Step- by step explanation:

Step 1:

We are given Jodi bought a new car with a 14-gallon gas tank. Around town, she can drive 336 miles on one tank of gas. She drove 448 miles on one tank of gas on her first trip traveling on highways.

Step 2:

Solve each simple inequality by dividing both sides by 14:

336\leq 14m and 14m\leq 448

\frac{336}{14}\leq  \frac{14m}{14} and \frac{14m}{14} \leq \frac{448}{14}

24\leq m and m\leq 32

Part D:

Answer:

The solution of the compound inequality is 24\leq m\leq 32

Step 1:

We are given Jodi bought a new car with a 14-gallon gas tank. Around town, she can drive336miles on one tank of gas. She drove 448 miles on one tank of gas on her first trip traveling on highways. To solve the compound inequality without rewriting it as two simple inequalities

Step 2:

Solving compound 336\leq 14m\leq 448 for m by dividing all sides by 14

226\leq 14m\leq 448\\

\frac{336}{14}\leq \frac{14m}{14}  \leq \frac{448}{14}

24\leq m\leq 32
