The length of an island is changing at the rate of –17 inches per year. How long will it take for the change in the length of the island to be –255 inches?

Answers

Answer:

15 years

Step-by-step explanation:

-255/-17=15

Based on the future dates concept, and the available content of the question, it will take 15 years for the change in length of the island to be -255 inches.

What is the Future date?

Future date is a term that is used to describe the major activities of a certain place or humans.

In this case, the time it takes for the change in length to be -255 inches we can set up the following equation:

Change in length = rate * time

-255 inches = -17 inches/year * time

To solve for time divide both sides of the equation by -17 inches/year:

time = -255 inches / (-17 inches/year)

Simplifying the expression:

time = 15 years

Therefore, in this case, it is concluded that it will take 15 years for the change in length of the island to be -255 inches.

A local farmer started the year with 56 farm animals. At the end of the year, the farmer had 63 farm animals. What was the percent of change? (Show work)

Answers

Answer:the percentage change is 7.

Step-by-step explanation:

The percentage is 7 because 63-56=7

Answer:

The answer is a increase of 12.5%

Step-by-step explanation:

The equation to find this is new minus old divided by old times 100, so it would be 63 minus 56 divided by 56 which gives you 7 over 56 times 100. 7 over 56 times 100 equals 12.5 so 12.5% is the answer

Make an equation that has the numbers : -3.78 , -1.2y, and -4.2y

Answers

Answer: In solution

Step-by-step explanation:

Well, first you need to arrange the numbers in anyway, separated by operations. I just did:

-3.78 + (-1.2y + -4.2y)

We then need to come up with the other side of the equation.

For this, I added the like terms:

-3.78 + (-1.2y + -4.2y) = -3.78 -5.4y

Then, I came up with a value for y. Y = 5

Then, I multiplied -5.4 by 5, getting -27 so,

-3.78 + (-1.2y + -4.2y) = -3.78 - 27

Again, I collected like terms:

-3.78 + (-1.2y + -4.2y) = -30.78

Now, I have my equation.

———————————————————————————————

HOW TO SOLVE THE EQUATION

-3.78 + (-1.2y + -4.2y) = -30.78

1. Add 3.78 to both sides

-1.2y + -4.2y = -27

2. Collect like terms

-5.4y = -27

3. Divide both side by -5.4

y = 5

Answer:-

-3.75 + -1.2y = -4.2y

Step-by-step explanation:

the answer would then be that y= 1.26 when solved
