Answer:

a ≤ 20/3

Step-by-step explanation:

Subtract 4 from both sides, obtaining:

-3a ≥ -20.  Dividing both sides by -3, we get a ≤ 20/3.

Note that because this is an inequality, and because we've divided all terms by a negative number, we must change the direction of the inequality symbol from ≥ to ≤.

Question 1

The number of ounces of jam that each jar can hold is 4 large jars and 2 small jars.

<h3>What is Matrix?</h3>

A matrix is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.

Here, from the given matrix by comparing the equations, we have:

l + 2s = 8    ...........(i)

l - s = 2      .............(ii)

Subtract the second equation from the first, to eliminate l

3s = 6

s = 2

Substitute 2 for s in l - s = 2

l - 2 = 2

Add 2 to both sides

l = 4

Thus, the number of ounces of jam that each jar can hold is 4 large jars and 2 small jars.

Kelsey is on a road trip, and is reading a map that has a scale of
ycow [4]

Answer:

Her actual distance for the trip will be 112.5 miles.

Step-by-step explanation:

You need to analize the information provided in the exercise.

You know that the scale of the map Kelsey is reading is:

2\ inches=50\ miles

And according to the exercise, Kelsey's trip measures 4.5 inches on that map.

 Therefore, in order to calculate what will  be her actual distance for the trip (Let be x this distance), you can set up the following proportion:

\frac{50\ miles}{2\ inches}=\frac{x}{4.5\ inches}

Finally, you must solve for x. Then, you get:

 \frac{(50\ miles)(4.5\ inches)}{2\ inches}=x\\\\x=112.5\ miles

 Therefore, her actual distance for the trip will be 112.5 miles
