5x + 20 = 90 - a = 90 - (3x + 40)
5x + 20 = 90 - 3x - 40 = 50 - 3x
5x + 3x = 50 - 20
8x = 30
x = 30/8 = 15/4

b = 3(15/4) + 40 = 45/4 + 40 = 51.25
The measure of a supplementary angle is 180 - 51.25 = 128.75

A rectangle has a length 10 more than its width. If the width is increased by 8 and the length by 4, the resulting rectangle has
Aleks [24]

The Solution to the problem of the rectangle is given below

For Part A:

  • equation model: (14 + w) * (w +8) = 132
  • Length = 15

For Part B

  • Perimeter = 46

Meaning of Perimeter

The perimeter of any shape can be defined as the total sum of the sides of the shape.

<h3>Analysis</h3>

For Part A

equation model= (14 + w) * (w +8) = 135

14w + 112 + 8w + w^{2} = 135

w^{2} + 22w - 23 = 0

solving the quadratic equation

w = -23 or 1

Because we are dealing with a physical quantity we will make use of the value 1

lenght of original rectangle = 10 + 1 = 11

Part B

Perimeter= 2(length) * 2 (breadth) = 2(11 + 4) * 2 (1 + 8)

Perimeter = 48

In conclusion, The Solution to the problem of the rectangle is given above.

1.) you have a credit card with an initial balance of $3,168 and an interest rate of 12.75 % APR if you make no payments on the
polet [3.4K]

Answer:

1.) [B]

2.) [C]

(3.) [D]                            

Step-by-step explanation:

1.) Initial amount = $3168

Annual percentage rate = 12.75

per month percentage rate = 1.06%

Interest after 3 months =  P*R*T/100

                                      = 3168*1.06*3/100

                                      = 100.74 (aprox)

Balance after 3 months = 3168-100.74

                                        = $3270.06 (aprox) (B.)

2.) Gross pay = $2759

Total interest rate = 7.65%+12%+7% =  26.65%

interest amount= 26.65% *2759 =$728.24 (aprox)

Housing and fixing expenses= $728.54  (C.)

3.) 1 hour = $8.25

1 week= 35 hours

3 weeks = 35*3 hours = 105 hours

Total income= 105 hours = $8.25*105= $866.25

Total interest to be deducted = 7.65+13+9 = 29.65 %

Income after deducting interest =  $866.25-256.843 = $609.407

(D.)
