Answer:

A. Both x\ge0,y\ge 0

Step-by-step explanation:

The local zoo is filling two water tanks for the elephant exhibit.

Let us assume that,

x = the number of hours the tanks are filling and

y = the number of gallons in the tank.

Tank one contains 34 gal of water and is filled at a constant rate of 4 gal/h. So the inequality function for this is,

y\ge 34+4x

Tank two contains 30 gal of water and is filled at a constant rate of 2 gal/h. So the inequality function for this is,

y\ge 30+2x

As number of hours and number of gallons can not be negative, so

x\ge0,y\ge 0

will be constraints to the system.

if eight times a number is increased by 3 the result is 19 more than six times this digit. find the number
Verdich [7]

Answer:

8

Step-by-step explanation:

Even though we don't know the number yet, let's name this number "n".

8n + 3 = 6n + 19

8n + 3 - 6n = 6n + 19 - 6n

2n + 3 = 19

2n = 16

n = 16/2

n = 8

Our number is 8.

Note: This answer is 100% correct.

In which situation would the appropriate unit of measure be kilometers?
lisabon 2012 [21]
Since you didn't list choices, I can only give you some guidance on the problem.

A kilometer is the length of 1000 meters. And a meter is about as tall as a normal desk height. So a kilometer is a relatively long distance compared to a desk.

It is also about half the length of a mile, or about 2 times around a normal athletic track.

Look for items that are long distance like that.
