Answer:

x=1

Step-by-step explanation: 9x+7=16

Subtract 7 from both sides.

9x=16−7

Subtract 7 from 16 to get 9.

9x=9

Divide both sides by 9.

​Divide 9 by 9 to get 1.

x=1

9x+7 when x=3

Plug 3 into the equation for the variable x

The price of one share of XYZ inc's stock drop by $0.02 on Monday. On Tuesday the price goes back up by $0.05.
Vsevolod [243]

Answer:

1.<u> </u>$(x+0.03) - $x

2. $ 34.21

Step-by-step explanation:

Let the price of XYZ inc's share to be = <u>$ x</u>

On Monday, the price drops by $ 0.02 = $ x- $ 0.02 = $ (x-0.02)

New price of shares on Monday is =<u> $ (x- 0.02)</u>

On Tuesday the price goes up by $0.05 = $ (x-0.02) + $ 0.05 = $(x-0.02+0.05)

New price on Tuesday = <u>$( x+ 0.03)</u>..............................................(a)

Change in price of one share of XYZ's stock= Price on Tuesday - price of share

                                         = <u> $(x+0.03) - $x</u>..........................................(b)

2. Give that x= $34.18  solve equation (a) above

Price on Tuesday at close of business= $ (x+0.03)

                                                               = $ (34.18+0.03)

                                                                = $ 34.21

Answer:

AB = 2.25

Step-by-step explanation:

Perimeter of square = 4L

24 = 4L

L = 24/4

L = 6cm

Hence the side length of square is 6cm

Area of square = L^2

Area of square = 6^2

Area of square = 36 sq. cm

Area of square = 1/2 * Area of the trapezium

36 = 1/2 * (AB+3AB)*8

72 = (AB+3AB)*8

72 = 4AB * 8

72 = 32AB

AB = 72/32

AB = 2.25
