A veterinarian divided 2/3 of a bottle of medicine equally among some sick cats. She gave each cat 1/3 of a bottle of medicine. How many sick cats were there?

Answers

Answer:

2 cats im pretty sure if you think about it you can divide 3/3 by 3cats and they use 2/3 of a bottle and where they give 1/3 to a cat it has to be 2 cats.

I think it is 2 because 1/3 times 2 is 2/3

simplify each expression by combining terms

Answers

Answer:

Combining like terms is actually pretty straightforward, you just have to combine like terms. In the problem 5c+2c, it would equal 7c since c is a common variable in this equation.

In the next question 16p+5+p-3x+6-x, it would equal 17p-4x+11 because 16p+p is 17p, -3x-x is -4x, and 5+6 equals to 11.

In the third question 18p+3-8p-5 would equal to 10p-2 since 18p-8p equals to 10p, and 3-5 equals to -2.

In the last question 9u+11v-22u+12v, it would equal to -13u+23v because 9u-22u equals to -13, and 11v+12v is 23v.

I hope this helped you!

7+c
17p-4x+11
10p-2
-13u+23v

What number should be added to both sides of the following equation to solve for x?

Answers

Answer:

X =14

Step-by-step explanation:

All numbers in degrees

1. because All triangles have internal angles that add up to 180

1) 180 - 90 = 90

1. you subtract 90 because all right angles = 90 and you have one right angle

2) 90 = 2x + 3x-20

2. subtract the other angles from the whole (90)

3) 90 = 5x - 20

3. combine like terms

4) 70 = 5x

4. Subtract 20 from whole

5. divide by 5 on both sides

5) X = 14

Hope this helped :)

x=14
angle cab= 28 because 2*14 = 28

Oceanside Bike Rental Shop charges a eleven dollar fixed fee plus nine dollars an hour for renting a bike. Melanie paid sixty - five dollars to rent a bike. How many hours did she pay to have the bike checked out? Let h represent the number of hours.

Answers

Answer:

She paid 6 hours for the bike to be checked out

Step-by-step explanation:

1. The equation is 11+9h=65. 11 represents the start value (fixed fee) and 9h represents how many hours she paid for, which is $65.

2. You subtract 11 from 65 to start figuring out how many hours she paid for. 65-11=54

3. You then divide 54 by 9 to calculate how many hours she paid. 6
