Answer: There are 180 dogs in the shelter.
Step-by-step explanation:
Let be "c" the number of cats in the shelter and "d" the number of dogs in the shelter.
You know that the total number of dogs and cats in the animal shelter is 275. Then you can express this with:
If the number of cats is 5 more than one half of the number of dogs, you can express it with:
Then, substitute into and solve for "d" to calculate the number of dogs that are in the shelter. Then:
If you are doing proportions which is fraction equal to fraction. It would be 300 over 10 is equal to s over 2.
The answer is
2y+6
Steps
3y+6+-y
(3y+-y)+(6)
Answer 2y+6
The exterior angles of a regular pentagon has a measure of 360-108= 252 degrees
the sum of these exterior angles will be 5*252=1260 degrees
a regular nonagon (9-gon) has the exterior angles measure of 360 -140 = 220 degrees
the sum of these exterior angles of a nonagon will be equal 9*220=1980 degrees
so from these result that
the sum of the measures of the exterior angles of a regular 5-gon is less than the sum of the measures of the exterior angles of a 9-on
hope this will help you
Answer:
Step-by-step explanation:
Given
(3x - 3) / 5 = (2x - 2) / 4
Begin by cross multiplying
Solution
- 4(3x - 3) = 5(2x - 2) Use the distributive property to remove brackets
- 12x - 12 = 10x - 10 Add 12 to both sides.
- 12x = 10x - 10 + 12 Combine the right
- 12x = 10x + 2 Subtract 10x from both sides
- 12x-10x = 2 Combine the left
- 2x = 2 Divide by 2
- x = 2/2
- x = 1
Note: the original equation gives you 0/5 = 0/4 which is 0 = 0.
