Answer:

dimensions of the book are 2 in. by 24 in.    

Step-by-step explanation:

I assume the book is a rectangle

Let w = the width

     l = the length

A = lw = 48         P = 2w + 2l = 52

                                   w + l = 26

                                          l = 26 - w

w(26-w) =48

26w - w^{2} = 48

w^{2}  - 26 w + 48 = 0

(w-2)(w -24) =  0

w = 2    or   w = 24

                           if w = 2, then l = 26 - 2 = 24

                           if w = 24, then l = 26 - 24 = 2

So, the dimensions of the book are 2 in. by 24 in.

First, rewrite 14/25 and 11/20 so that they have a common denominator. Then, use <, =, >
muminat

Answer: 14/25 = 56/100

               11/20 =  55/100

               14/25 > 11/20

Step-by-step explanation:

The least common multiple of 20 and 25 is 100.

(100 = 20*5, 25*4)

So we can take the common denominator 100.

14*4/25*4 =56/100. ∴14/25 = 56/100

11*5/20*5  =55/100. ∴11/20  = 55/100

56>55

∴56/100 > 55/100

∴14/25 > 11/20

Hope it's good;)

The sum of 3 integers is 194. the sum of the first and second integers exceeds the third by 80. The third integer is 45 less tha
kirill115 [55]
Let
x = first integer
y = second integer
z = third integer
First equation: x + y + z = 194
Second equation: x + y = z + 80
Third equation: z = x - 45

Let's find the values of x, y and z.
Substitute 3rd eq to 1st eq:
x + y + x - 45 = 194
2x + y = 45 + 194
y = -2x + 239

Plug in both we have solved for y and the 3rd eq to the 2nd eq to find x
x + (-2x + 239) = (x - 45) + 80
x - 2x - x = -45 + 80 - 239
-2x = -204
x = -204/-2
x = 102

Solving for y,
y = -2(102) + 239
y = 35

Solving for z,
z = 102 - 45
z = 57
