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.

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.

14- straight line across x-axis on -3

Answer:

The correct answer is 135

Step-by-step explanation:

This is because her rate is 15 flowers per 5 minutes, and there is 45 minutes. Therefore, 5 minutes occurs 9 times in 45 minutes and fifteen flowers times 9 groups of five minutes is 135.

Answer:

135

Step-by-step explanation:

Because if it took 5 mins to plant 15 flowers, you can count how many 5's there are in 45 which there is 9 fives In 45 so, 15x9=135 and therefore she planted 135 flowers in 45 minutes :)

Answer:

step 3

Step-by-step explanation:

He should have subtracted 15 instead off adding 15. this would have gotten rid of the fifteen on the right side and left him with -17=b. Instead, he would have added 15 and gotten 13=30+b. That threw off the rest of the equation. The rest of the equation is wrong. b should equal -17

the slope-intercept equations should be y=3x-17

Answer:9

Step-by-step explanation:

The range is the simplest measurement of the difference between values in a data set. To find the range, simply subtract the lowest value from the greatest value, ignoring the others.

Your answer, in this case, is 9. If your largest number is 10 and the smallest is 1.

10-1=9

Answer:

9

Step-by-step explanation:

The range is the simplest measurement of the difference between values in a data set.  So 10-1 is 9

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

Answer:

[tex]2~2/9[/tex] gallons per minute

Step-by-step explanation:

If it drains at a rate of [tex]x[/tex] gallons in [tex]y[/tex] minutes, the tub drains [tex]x/y[/tex] gallons in [tex]1[/tex] minute.

We can plug in for [tex]x[/tex] and [tex]y[/tex] for this equation!

The amount it drains in one minute is [tex]5/(2~1/4)=5/(9/4)=20/9=2~2/9[/tex].

So, the answer is [tex]\boxed{2~2/9}[/tex] gallons per minute.

The quantity of water that drains out of the tub each minute is 2.23 gallons.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that water drains out of the bathtub at a rate of 5 gallons in 2¹/₄ minutes.

2¹/₄ minuts = 5 gallons

1 minute = 5 / 2¹/₄

1 minute = 5 /2.25

1 minute = 2.23 gallons

Therefore, the quantity of water that drains out of the tub each minute is 2.23 gallons.
