Answer:

■ A random sample of dogs at different animal shelters in Abu Dhabi shows that 12 of the 60 dogs are puppies. Abu Dhabi's animal shelters collectively house 1,200 dogs each year. About how many dogs in all of the city’s animal shelters are puppies?

➢12/60 are puppies. 60 are the number of dogs, 12 is number of puppies.

If there are 1200 dogs, we focus on the 60. 1200/60= 20

Whatever we do to the denominator we do to the numerator, so since we can multiply 60 by 20 to get 1200; we need to multiply 12 by 20 to get the total number of dogs. Which is 240.

60/1200 = x/20 1200x /1200 =12/20 x =240

Answer:

240

Step-by-step explanation:

1) First you set up a proportion.

2) You do 12/60=x/1,200.

3) You cross multiply and do 12x1,200. Your answer is 14400.

4) Then you do 14400/60=240

Answer:

Step-by-step explanation:

if you take the number of paws minus the number of noses you get your answer so if you take

24 - 6 ( noses) =18

(4paws x6 lions= 24)

so the number of lions is 6

What is the solution of square root 1-3x = x+3

hram777 [196]

Answer:

Step-by-step explanation:

I hope the given equation is :

First step to solve this equation to remove square root from the left side. So, take square on each sides of the equation. Therefore,

1 - 3x = (x + 3)²

1 - 3x = (x + 3)*(x + 3) Since a² = a * a

1 - 3x = x² + 3x + 3x + 3² By multiplication.

1 - 3x = x² + 6x + 9 Combine the like terms.

x² + 6x + 9 - 1 + 3x = 0 Subtract 1 and add 3x from each sides of equation

x² + 9x + 8 = 0 Combine the like terms.

Next step is to factor the trinomial to solve the above equation for x.

For that break downn the constant 8 into two multiples so that the addition of the multiples will result the coefficient of x = 9.

So, 8 = 1 * 8

Addition of 1 and 8 will give 9. So, next step is to replace 9x with 1x + 8x. So,

x² + 1x + 8x + 8 = 0

(x² + 1x) + (8x + 8) = 0 Group the terms.

x ( x + 1) + 8 (x + 1 ) = 0 Take out the common factor from each group.

(x +1 ) ( x + 8 ) = 0 Take out the common factor (x + 1).

So, x + 1 = 0 and x + 8 = 0 Set up each factor equal to 0.

Hence, x = -1 and - 8.

Next step is to plug in -1 and -8 in the original equation to cross check the solutions.

For x = -1,

Simplify each sides separately.

2 = 2

2 = 2 is correct. So, x = -1 satisfy the equation

Hence, x = -1 is the real solution of the given equation.

Similarly let's plug in x = -8 now. So,

Simplify each sides separately.

5 = 2

5 = 2 is not true. So, x = -8 is the extraneous solution.

Therefore, the only solution is x = -1.

Hence, the correct choice is C.

Hope this helps you!
