3c + 2 = 3c + 2

please help me

Answers

Answer:

3c+2=2+3c

Step-by-step explanation:

1. Subtract 2 from both sides of the equation

3c + 2 = 3c + 2
3c + 2 - 2 = 3c + 2 - 2

2. Simplify by subtracting the numbers

3c + 2 - 2 = 3c + 2 - 2
3c = 3c

3. Subtract 3c from both sides of the equation

3c = 3c
3c - 3c = 3c -3c

4. Simplify by combining like terms

The Hendrix family was draining their pool at the end of
summer. They found that the water level goes down by 0.4
feet every hour. If the water level in the pool has changed by
-1.4 feet, how long have they been draining the pool?

Answers

Answer:

3.5 hours

Step-by-step explanation:

If the water goes down by 0.4 feet every hour

we can add 0.4 + 0.4 + 0.4 (0.4 x 3) and get 1.2 and 1.4 - 1.2 - 0.2

And we also know that half of 0.4 is 02 so we can add 0.2 to 1.2 in order to get our desired answer. Which is 1.4 So now let's add what we multipleied by

Max car holds 18 gallons of gasoline driving on the highway the car uses approximately 2 gallons per hour. let H represent the number of hours max has been riding on the highway. write an expression that shows how many gallons of gasoline Max has left after driving H hours. then find the number after max drives 3.5 hours on the highway.

Answers

y= 18 gallons-2(h)
y is what you're trying to find out and since there are 18 gallons in the tank after every hour you would have 2 less gallons. So, you can multiply how many hours he's been driving by the 2 gallons and subtract it from 18

y = 6/5x -5

Step-by-step explanation:

Points are (5,1) (0,-5)

-5 - 1/ 0-5 = 6/5 slope

y-y1= m(x-x1)

y- 1 = 6/5(x-5)

y -1 = 6/5X - 6

y = 6/5X -5

Answer:

21 square feet

Step-by-step explanation:

To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.

Version 1: 6 * 2 rectangle and 3 * 3 square

(6 * 2) + (3 * 3)

12 + 9

21 sq. ft.

Version 2: 5 * 3 rectangle + 2 * 3 rectangle

(5 * 3) + (2 * 3)

You could really just do 7 * 3 here.

7 * 3

21 sq. ft.

Either way, you still get 21 square feet as your answer.

5 positive integers are arranged in ascending order, as follows:
7, 8, 11, 11, X
The median and the range are equal.
Find 2.

Answers

Answer:

X = 18.

Step-by-step explanation:

The median = 11 so the mean is also 11 (given).

So mean  = 11 = (7 + 8 + 11 + 11 + X) / 5

(37 + x)/ 5 = 11

x + 37 = 55

x = 55 - 37 = 18.

whats the answer to 3x+4=6x+19

Answers

Answer:

x = -5

Step-by-step explanation:

[tex]3x + 4 = 6x + 19\\-3x + 4 = 19\\-3x = 15\\x = -5[/tex]

3x+4=6x+19 subtract 3x from both sides
4=3x+19 subtract 19 from both sides
-15=3x divide by 3 on both sides
-5=x
The answer is x=-5

Which expression has the same value as 8 – (-1)?​

Answers

Answer: 9

Step-by-step explanation:

Two negatives make a positive. So the expression 8-(-1) is equal to 9, because the two subtraction signs the equation create an addition sign, and the equation becomes 8 + 1.

Therefore, 9 has the same value as 8-(-1).

The previous Activities have provided you with an economic and ethical basis for evaluating kidney-transplant policies. Now it is time for you to be the policy maker. Read the following information and then decide which policy you support. Be ready to justify your decision. Which policy saves the most lives? Which conforms most closely to the ethical framework you find most acceptable?OPTION 1: THE CURRENT SYSTEMA national law makes it illegal to sell human organs. Anyone who sells a kidney faces jail, fines or both. People may donate kidneys, however, and doctors dis-tribute donated kidneys on the basis of need. Some of the factors they consider in allocating kidneys are the patients age and medical condition, how long the patient has been on a waiting list and whether the donor is in the local area.Under this system, there is a shortage of kidneys, and many people are on a waiting list for years. During this time they receive costly dialysis treatment, and many people die.OPTION 2: AN OPEN MARKETCreate an open market in kidneys. People may sell their kidneys on the mar-ket for the highest price they can get. They may sell and deliver a kidney while they are still alive, or they may sell for delivery after they die. Brokerage firms match buyers and sellers. People could even sell kidneys on eBay. Recipients would pay for the kidney the same way they pay for other medical care: with their own funds or through insurance, government programs and charity.OPTION 3: A REGULATED MARKETCreate a market in which anyone may sell a kidney, but only authorized insti-tutions such as hospitals may legally buy. This option reduces the possibility of acquiring kidneys through involuntary means such as theft or murder. The institutions would allocate the kidneys on a basis similar to the way kidneys are allocated today using age, medical need or time spent on a waiting list. Recipients would pay for the kidneys with private funds, insurance, government assistance and charity.OPTION 4: A COMMUNITARIAN APPROACHThis approach uses nonmarket mechanisms to increase the supply in several ways.A marketing campaign would increase peoples awareness of the issue and alter their preferences for organ donation through moral persuasion. The slogan for a national television campaign might be Friends dont let friends waste the gift of life. This is not an appeal to altruism but to peoples sense of moral obliga-tion and duty.A more authoritarian policy would legally mandate that when people die, all their organs will be donated unless they indicate otherwise. People who dont want to donate must take the extra step to note this in advance on their driv-ers license. Today people must agree in advance for their organs to be donated.2 -3 paragraphs -1 2/3 divided by (-2 1/5) Freee easy PIONT just ps there are 2 ez questions Roberto is cutting 3 loaves of homemade bread into halves to give to his neighbors.
