-2 -13.8x = -8 -(6x+1)
Varvara68 [4.7K]
-2 -13.8x = -8 -6x -1
First, I distributed the negative 1 that was outside of the parentheses to the positive 6x and the positive 1.

-2 -13.8x = -9 -6x
Then I added the negative 8 to the negative 1 which equals negative 9.

-2 -13.8x +6x = -9 -6x +6x
After that I used the addition property and added a positive 6x to both sides.

-2 -7.8x = -9
Then simplifying.

+2 -2 -7.8x = -9 +2
After simplifying, I used the addition property again, adding a positive 2 to both sides.

-7.8x = -7
Simplified.

-7.8x (-1) = -7 (-1)
Then I multiplied both sides by with a negative 1 since the variable cannot be a negative.

7.8x = 7
Simplified

(1/7.8) 7.8x = (1/7.8) 7
Then, to isolate the veriable, I multiplied 1/7.8 to both sides.

ANSWER THIS PLEASE ASAP
Talja [164]

Answer: a.) 72 of each type of animal, for a total of 216

b.) 16 grown cats, 4 kittens

Step-by-step explanation:

part a. It's a distribution (division) problem. The same number of each animal is distributed over some unknown number of troughs, but the total number of troughs adds up to 69. ( I hate to give this all away, as its a brilliant problem! )

Number of troughs for each animal type is How many needed by the number of animals per trough:

h/2 + c/3 + p/8 = 69  

Since we are given "the same number of horses, cows and pigs" we can substitute "x" for all.

\frac{x}{2} + \frac{x}{3} +\frac{x}{8} = 69    Get a common denominator. 24 would work, 48 also.

48(\frac{x}{2} +\frac{x}{3} +\frac{x}{8} ) = 48(69)

24x + 16x + 6x = 3372

46x = 3372    x = 72

Proof:  calculate the number of each kind of trough

Horses 72/2 = 36, Cows 72/3 = 24  Pigs 72/8 = 9    36+24+9 = 69

part b.  5c + 3k = 92,   c + k = 20  Rearrange to get a value for c to substitute.

c = 20-k   5(20-k) +3k =92  Distribute and solve

100 - 5k + 3k = 92 becomes -2k = -8  so  k = 4 Substitute into the original

c + 4 = 20  becomes c=20-4,  so c = 16

Proof: 5c +3k = 92 Substitute values 5(16) + 3(4) = 92  80 + 12 = 92
