Terry has won 18 of 35 chess games. Sandra has won 24 of 36 chess games. Terry wants to know how many of the remaining games she would have to win for her winning percentage to be greater than Sandra's, given that Sandra doesn't win any more games. Let x represent the number of games remaining, and let y represent the number of games Terry needs to win. Which inequality represents this situation?

a. 18+x/35+x > 24/36+x

b. 18+y/35+x > 24/36+x

c. 18+y/35+x > 36+x/24

d. 35+y/18+x > 24/36+x

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places

the answer is c 150
