Answer:

Step-by-step explanation:

(w +5)/-3 = (-2w +6)/4 . . . . . . . given

4(w +5) = -3(-2w +6) . . . . . . . . multiply by -12

4w +20 = 6w -18 . . . . . . . . . eliminate parentheses

38 = 2w . . . . . . . . . . add 18-4w

19 = w . . . . . . . . . . divide by 2

Three merchants find a purse lying in the road. The first asserts that the discovery would make him twice as wealthy as the othe

Angelina_Jolie [31]

Answer: the system of equation would be :

A + Y = 2 (B+C)

B + Y = 3B

C + Y = 5C

the three merchants would have 10 dollars, 10 dollars, and 5 dollars respectively

Step-by-step explanation:

before finding the purse, lets assume the wealth of the 3 merchants were as follows:

first merchant = A dollars

second merchant = B dollars

third merchant = C dollars

lets assume the purse contained Y dollars

After finding the purse they all claimed they would have the following:

first merchant said adding the money in the purse to his wealth would make him twice as rich as the other two combined : A + Y = 2 (B+C)

second merchant said adding the money in the purse to his wealth would make his wealth triple : B + Y = 3B

third merchant said adding the money in the purse to his wealth would make his wealth increase five folds : C + Y = 5C

third merchant = C dollars

therefore the system of equations to represent the problems are:

A + Y = 2 (B+C)

B + Y = 3B

C + Y = 5C

2. now when the money in the purse is 20 dollars (Y= 20 dollars ), from the equations above

the second merchant will have :

B + Y = 3B

B + 20 = 3B

3B - B = 20

2B = 20

B = 10 dollars

the third merchant will have :

C + Y = 5C

C + 20 = 5C

5C - C = 20

4C = 20

C = 5 dollars

the first merchant will have :

A + Y = 2 (B+C)

A + 20 = 2 ( 10 + 5)

A = 2 (15) - 20

A = 30 - 20

A = 10 dollars

Tennis balls are sealed in a pressurized container to maintain the rebound percentage

Darina [25.2K]

Answer:

Rounding the results to the next hundredth, we have:

Bounce 1: 2 * 0.55 = 1.10 meters

Bounce 2: 1.10 * 0.55 = 0.61 meters

Bounce 3: 0.61 * 0.55 = 0.34 meters

Bounce 4: 0.34 * 0.55 = 0.19 meters

Bounce 5: 0.19 * 0.55 = 0.10 meters

Bounce 6: 0.10 * 0.55 = 0.06 meters

Bounce 7: 0.06 * 0.55 = 0.03 meters

Step-by-step explanation:

Rebound percentage = 55% = 0.55

Bounce 1: 2 * 0.55 = 1.10 meters

Bounce 2: 1.10 * 0.55 = 0.605 meters

Bounce 3: 0.605 * 0.55 = 0.33275 meters

Bounce 4: 0.33275 * 0.55 = 0.1830125 meters

Bounce 5: 0.1830125 * 0.55 = 0.10065688 meters

Bounce 6: 0.10065688 * 0.55 = 0.05536128 meters

Bounce 7: 0.05536128 * 0.55 = 0.0304487 meters

Rounding the results to the next hundredth, we have:

Bounce 1: 2 * 0.55 = 1.10 meters

Bounce 2: 1.10 * 0.55 = 0.61 meters

Bounce 3: 0.61 * 0.55 = 0.34 meters

Bounce 4: 0.34 * 0.55 = 0.19 meters

Bounce 5: 0.19 * 0.55 = 0.10 meters

Bounce 6: 0.10 * 0.55 = 0.06 meters

Bounce 7: 0.06 * 0.55 = 0.03 meters
