Answer:

a) x=2

b)x=12

c)x=5/4

Step-by-step explanation:

a)5x-2=8

5x=8+2

5x=10

x=2

b)4x-3=2x+9

4x-2x=9+3

2x=12

x=6

c)6x+3=2x+8

6x-2x=8-3

4x=5

x=5/4

Proof:

a)5x-2=8

5(2)-2=8

10-2=8

8=8

b)4x-3=2x+9

4(12)-3=2(12)+9

48-3=24+9

45=45

c)6x+3=2x+8

6(5/4)+3=2(5/4)+8

30/4+3=10/4+8

15/2+3=5/2+8

10.5=10.5

Hope this helps ;) ❤❤❤

Answer:

5−x²+2xy−y²

Step-by-step explanation:

5 - (x-y)²

Rewrite  

(x−y)² as (x−y)(x−y) so

5−((x−y)(x−y))

Expand (x−y)(x−y) using the FOIL Method

Apply the distributive property.

5−(x(x−y)−y(x−y))

Apply the distributive property

5−(x⋅x+x(−y)−y(x−y))

Apply the distributive property

5−(x⋅x+x(−y)−yx−y(−y))

Simplify and combine like terms  

Simplify each term

5−(x²−xy−yx+y²)

Subtract yx from −xy  

5−(x²−2xy+y²)

Apply the distributive property

5−x²−(−2xy)−y²

Multiply  −2 by −1

5−x²+2xy−y²

The pound has three kinds of dogs: pit bull, chihuahuas and mutts. All but 23 of the dogs are pit bull, all but 17 are chihuahua
Georgia [21]

Answer:

There are 68 dogs in the pound.

Step-by-step explanation:

Number of pit bull dogs in a pound = P = 23

Number of chihuahuas dogs in a pound = C = 17

Number of mutts dogs in a pound = M = 28

Total number of dogs in a pound = T

T = P+C+M=23+17+28=68

There are 68 dogs in the pound.
