y+16= -8
Another Question heheh

Answers

Answer:

y = -24

(mark me brainliest)

y=-24
To solve this you need to get y by itself so you have to move 16 to the other side. To do this you are doing to do the opposite of what it says so since on that side it’s addition you are going to subtract. Subtract 16 from 16 which cancels it out, then subtract 16 from -8 to get -24. Now you have y=-24

Mrs. Banet walked 48 laps in 3 hours. How many laps did she walk in two hours?

Rate Answer Choices
48 laps to 3 hours
48 to 3

Unit Answer choices
16 laps
16 laps 1 hour

How many laps did she walk in 2 hours?
Answer choices
48
16
32

Answers

the answer would be 32 laps in 2 hours. This is because if you walk 48 laps in 3 hours then you would have to figure out how many laps Mrs. banet walks in 1 hour. To do that you divide 48 by 3 and get 16 laps so 16 multiplied by 2 equals 32 which is how much you walk in 2 hours. Hope this helps :)

D. Phone service costs $5.00, and an additional 5 cents for each minute.

You can choose more than one answer.....

Answers

I'd say A, D, and B.

However, I would choose answers at a CONSTANT because, what if you need to divide or multiply or something, let's say Derek runs 5 miles per 1 hour, you'd have to divide. Yet, I recommend these three answers.

Answer: A. Hayley runs at a pace of 1 mile every 8 minutes.

The ratio of keepers to animals in the city zoo is 2 : 7. 12 keepers and 42 animals. If 21 more animals are added, how many total keepers are needed to maintain the ratio of keepers to animals?

A. 16

B. 17

C. 18

D. 19

E. 20

Answers

Answer:

C: 18

Step-by-step explanation:

All you have to do is write down the ratio. Then you find out that 21 is half of 42 so that means that the amount of zookeepers that you will have to add should be half the amount as well so instead of 12 it would be 6. Then you just add the two numbers together to get your final answer of 18.

The answer is 18 keepers

Find the equation of the line that contains the points (-5, 0) and (-3, 4)

Answers

Answer:

y = -1/2x - 5/2

Step-by-step explanation:

With points (-5,0) and (-3,4), we need to find the slope first.

[Find slope of points]

Using slope formula m = (Y2 - Y1) / (X2 - X1)

Using points: m = (4 - 0) / (-3 - 5) = 4/-8 = -1/2

[Use point-slope formula]

(y-y0) = m(x-x0)

Using points: (y - 0) = -1/2(x - -5)

Finally: y = -1/2x -5/2
