Answer:

∴At the beginning of the game Sparrow had = (70+12)=82 coins

Step-by-step explanation:

Given , three pirates named Ahab, Sparrow and Davy play a game.

Let at the end of the game Ahab, Sparrow and Davy  have 4x, 5x,and 6x coins respectively.

Total number of coins= 4x+5x+6x=15x

Again given that the pirates have a total of 210 coins.

According to the problem,

15x =210

⇔x = 14

Therefore, Ahab, Sparrow and Davy  have(4×14)=56,(5×14)=70 and (6×14)=84 respectively.

Since,Ahab has won 5 coins and Davy has won 7 coins.This(7+5)=12 coins was belonged to Sparrow.

∴At the beginning of the game Sparrow had = (70+12)=82 coins

Answer:

The answer to number one is 3 1/2, the answer to number two is 3 1/3, the answer to number three is 1 1/4, the answer to number four is 1 3/5, the answer to number five is 3 1/5, the answer to number six is 19/4, the answer to number seven is 27/5, the answer to number eight is 35/3, the answer to number nine is 24/7, and the answer to number ten is 13/6.

Step-by-step explanation:

To change an improper fraction into a mixed number, you hate to divide the numerator by the denominator. For example, if the improper fraction was 10/5, you would get 2 because 5 goes into 10 two times. If the improper fraction was 8/5, you would do the same thing and get 1 3/5 because 5 goes into 8 once, and since 8 minus 5 is 3, you get 3 over 5.

To change a mixed number into an improper fraction, you have to multiply the denominator my the whole number, and then take that number and add it by the numerator. For example, if the mixed number was 8 2/3, the improper fraction would be 26/3 because 3 times 8 is 24, and 24 plus 2 is 26.

I hope this helps you have a wonderful day :D

if p(x)=x*2-1 and q(x)=5(x-1),which expression is equivalent to (p-q)(x)?
umka2103 [35]

Answer:

(p - q)(x) = (x -1) (x - 4)

Step-by-step explanation:

Given

p(x) = x^2 - 1

q(x) = 5(x - 1)

Required

(p - q)(x)

This is represented as:

(p - q)(x) = p(x) - q(x)

(p - q)(x) = x^2  - 1 - 5(x - 1)

(p - q)(x) = x^2  - 1 - 5x + 5

Collec like terms

(p - q)(x) = x^2  - 5x + 5 - 1

(p - q)(x) = x^2  - 5x + 4

Expand

(p - q)(x) = x^2 -4x - x + 4

Factorize

(p - q)(x) = x(x -4) - 1(x - 4)

(p - q)(x) = (x -1) (x - 4)
