Ira Lisetskai [31]

Step-by-step explanation:

14) percentage of increase

% of increase = (new - original)/original × 100

= (40 - 35)/35 × 100

= 5/35 × 100

= 14.285% = 14% increase

15) percentage of decrease

% of decrease = (original - new)/original × 100

= (16 - 10)/16 × 100

= 6/16 × 100

= 37.5% = 38% decrease

16) percentage of increase

% of increase = (new - original)/original × 100

= (73 - 27)/27 × 100

= 46/27 × 100

= 170.37% = 170% increase

17) percentage of decrease

% of decrease = (original - new)/original × 100

= (92 - 21)/21 × 100

= 71/21 × 100

= 338.10% = 338% decrease

18) percentage of decrease

% of decrease = (original - new)/original × 100

= (21.2 - 10.8)/21.2 × 100

= 10.4/21.2 × 100

= 49.06% = 49% decrease

19) percentage of increase

% of increase = (new - original)/original × 100

= (25 - 11)/11 × 100

= 14/11 × 100

= 127.27% = 127% increase

20) percentage of increase

% of increase = (new - original)/original × 100

(76 - 68)/68 × 100

8/68 × 100 = 11.77% = 12%

21) percentage of increase

% of increase = (new - original)/original × 100

= (40 - 21)/21 × 100

= 19/21 × 100

= 90.47% =90%

22) New car = AED 45,500

Used car = x

New car = (25% of x) + x

45,500 = (25x/100) + x

45,500 = (25x + 100x)/100

45,500 = 125x/100

45,500 × 100 = 125x

4,550,000 = 125x

x = 4,550,000/125 = 36,000

x = AED 36,000

-2x-2y=-8<br> -4x-8y=-20
Citrus2011 [14]

Answer:

-2x-2y=-8

-4x-8y=-20

From the 1st eqn

Dividing through by 2

you have

-x-y=-4

Multiply through by -(minus)

x+y=4

x=4-y

Substitute into eqn 2

-4x-8y=-20

-4(4-y)-8y=-20

-16 + 4y - 8y = -20

-4y = -20 +16

-4y = -4

y= 1

Substitute into any of the other eqn's to get x

x= 4-y

x= 4-1

x=3
