Answer:

<h2>3x = -24</h2>

Step-by-step explanation:

-9(x+3)-2x=-5(2x+3)-4\qquad\text{use distributive property}\\\\(-9)(x)+(-9)(3)-2x=(-5)(2x)+(-5)(3)-4\\\\-9x-27-2x=-10x-15-4\qquad\text{combine like terms}\\\\(-9x-2x)-27=-10x+(-15-4)\\\\-11x-27=-10x-19\qquad\text{add 27 to both sides}\\\\-11x=-10x+8\qquad\text{add 10x to both sides}\\\\-x=8\qquad\text{change the signs}\\\\x=-8\qquad\text{multiply both sides by 3}\\\\3x=-24

A farmers productions statistics finds that it takes 2 chickens to produce 6 eggs in 24 hours. How many chickens will be needed
Lelu [443]

Answer:

8 chickens

Step-by-step explanation:

Firstly, we need to know the number of eggs produced by a single chicken in 24 hours.

Since 2 chickens produce 6 eggs in 24hours, this means 1 chicken will produce 3 eggs in 24 hours.

Now, we need 24 eggs to be produced. Since the time is the same 24hours, meaning time is constant, the number of chickens required to produce 24 eggs will be 24/3 = 8 chickens

Hence, we can say that 8 chickens will produce 24eggs in 24 hours

There are about 76.9 million pet dogs and 87 million pet cats in the United States. The number of pet dogs is what percent less
Dmitriy789 [7]

Answer:

The number of pet dogs are 11.61% less than the number of pet cats.

Step-by-step explanation:

Number of pet dogs in the United states = 76.9 million

Number of pet cats in the United states = 87 million

Difference between the number of cats and dogs :

=87 million- 76.9 million = 10.1 million

Percentage of number of pet dogs less than pet cats:

=\frac{\text{Difference}}{\text{Number of cats}}\times 100

=\frac{10.1 million}{87 million}\times 100=11.61\%

The number of pet dogs are 11.61% less than the number of pet cats.
