Find x and y. Please

Answer:

x = 4       y = 21

Step-by-step explanation:

16x - 23 = 10x + 1

16x - 10x = 23 + 1

6x = 24

24/6 = x

x = 4

16(4) - 23 = 41

41 + (180 - 62) + y = 180

41 + 118 + y = 180

y = 21

Can someone please explain the Associative Property, and Distributive Property to me? I understand the Commutative Property and
Anettt [7]

The associative property is basically just when you move the parentheses in a problem. For example: (a+b)+c = a+(b+c).

Distributive property is a little more complicated, its better if i show you.

a(b+c) = ab+ac

so a times b plus c is the same as a times b plus a times c.

Hope i helped:)

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
