The perimeter of the top of a desk is 54 inches if the length of the desk is 15 inches what is the width of the desk

The width of the desk is 12 inches.

Step-by-step explanation:

Given:

The perimeter of the top of a desk is 54 inches.

The length of the desk is 15 inches.

Now, to find the width of the desk.

Let the width of the desk be .

Putting the formula of perimeter to get the width:

⇒

⇒

Subtracting both sides by 30 we get:

⇒

Dividing both sides by 2 we get:

⇒

⇒

Therefore, the width of the desk is 12 inches.

if x decreases by 4 then y increases by 10

step-by-step explanation:

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
