The length of a picture frame is 2 inches more than the width. The perimeter of the frame is 36 inches. What is the length of th

ollegr [7]

Answer in one complete sentence:
____________________________________________
   "The length of the frame is ten (10) inches."
_____________________________________________
Explanation:
_____________________________________________
Perimeter = P = 36 in.
Length = L = 2 +2
Width = w .
_____________________________________________
These are the two equations for the system of equations:

P = 2L + 2w = 36 in.
L = 2 + w
_____________________________________________
Solve for "L" (length) of the frame.
______________________________________
In the equation:
______________________________________
P = 2L + 2w = 36.

{Note: standard knowledge; and/or look up:
______________________________________
Formula for the Perimeter of a rectangle: P = 2L + 2w} ;
_______________________________________
We are given: P = 36 in.

Rewrite, substituting "2+w" for "L" ;

P = 2(2+w) + 2w = 36 ;
___________________________
Note: 2(2+w) = 2*2 + 2w = 4 + 2w .

Now, Rewrite the equation, substituting "(4 + 2w) for "2(2+w)" ;
__________________________________________________
P = (4 + 2w) + 2w = 36 ;

P = 4 + 2w + 2w = 36 ;

Combine the "like terms" ;
____________________________________________
+ 2w + 2w = 4w ;
____________________________________________
   P = 4 + 4w = 36 ;
____________________________________________
↔   4 + 4w = 36 ;
____________________________________________
Subtract "4" from EACH SIDE of the equation:
____________________________________________
→ 4 + 4w − 4 = 36 − 4 ;
____________________________________________
to get:
____________________________________________
            →  4w  = 32 ;
____________________________________________
            → Divide EACH SIDE of the equation by "4" ; to isolate "w" on one side of the equation; and to solve for "w" ;
____________________________________________
            → 4w / 4 = 32 / 4 ;

               → w = 8 .
____________________________________________
Now, to solve for: "L" (the length).
____________________________________________
    Length: L = 2 + w ;

                 → L = 2 + 8 = 10 inches.
____________________________________________

Question 1

Airida [17]

Answer:

a) There are Total 25 Question on the test.

Each question is worth 4 points.

b) Your friend answered 19 questions correctly.

Step-by-step explanation:

Given:

Question answered =24

Percent earn = 96%

Total point test = 100

We will first solve for part a.

We need to find Total Question on the test and Points worth each question.

Now We know that percent earn is equal to Question answered divided by Total Question on test and ten multiplied by 100.

Framing in equation form we get;

$Percent\ earn = \frac{\textrm{Question Answered}}{\textrm{Total question on test}}\times 100\\ \\\textrm{Total question on test} = \frac{\textrm{Question Answered}}{\textrm{Perecent earned}}\times 100$
