if the ratio of dogs to cats is 1 to 2 and there is a total of 21 animals how many are dogs

Answers

Answer:

Step-by-step explanation:

Let   cats = x  and dogs = y

and given conditions are ,

dog: cat= 1:2

y:x=1:2

y/x = 1/2

x=2y

also given that

total animals = 21

x+ y=21     putt x=2y we get

2y +y =21

3y = 21

y = 7  Dogs

putt y = 7 in above equation we get

x+7=21

x=14 Cats
There are 7 dogs and 14 cats

Every one dog there are two cats 1:2
Also could be written as (cats) 7:12 (dogs)

You will need 120 feet of fencing to put all the way around a rectangular garden. The length of the garden is 40 feet. What is the width?


A. 20 feet


B. 40 feet


C. 4,800 feet


D. 80 feet

Answers

Answer:

A. 20 ft

Step-by-step explanation:

(120/2)-40=20

Answer:

a) 20 feet

Step-by-step explanation:

We know it's a rectangle so lengths are the same and widths are the same

If length is 40

That would mean 120-2(40) = 80

We know 2 widths of a rectange so 40/2 is 20

Therefore 20 feet.

Answer:

2x - 10 = 10 - 3x

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4

Simplifying

x = 4

Does anyone also understand this?

Answers

Answer:

See explanation

Step-by-step explanation:

So, the angle for QRS is the interior angle of R. The exterior angle outside of angle R is for the equation you are going to use. Because angle R is on a straight line, the interior angle of R plus the exterior angle of R will equal 180 degrees. From there you should be able to calculate the rest of the angles, I believe you should be able to calculate y first.

All of the angles in a triangle add up to 180. From there you make an equation which would give you the value of y.

We know that the bottom line is straight, so it equals 180*. QRS is supplementary to the R* angle, which is 144*. All supplementary angles add up to 180, so 180-144 would give us 36* for the Value of QRS.

Now we know QRS=36* and the sum of all the angles is 180, we can write the equation
6y + 36 =180
y= 24

Now you plug the y in ... giving you the value of angle S to be 24* and angle Q to be 120.

QRS = 36*
Q= 120

a) y=-3/4x+4

b) y=-3/4x+2

c) y=-3/4x+1

Answers

Answer:

Step-by-step explanation:

1. y = -3/4 +4 cause that is the same line as the equation and since they are the same line it would mean there would be infinitely many solutions.

2. y=-3/4x+2 if you graph this line next to the orginal line it runs through (0,1) and you can see that its paralellel and will never meet the other line so there will be no solutions

3. for this question im confused because none of the answers fits the line that the question is asking for the closest would be y= -3/4x+2 since it runs through (0,2) but other than that none of the answers fit the line its describing.

an equation that would work though would be y=-1/4x+2
