Three teams, A, B and C, play in a competition
games won by A: games won by B = 3:1
games won by B: games won by C = 5:1
Team B has won 10 games.
In total, how many games have the three teams won?
Your final line must say, Total games won = ...​

el mani y el 123,189

Step-by-step explanation:

10987:198.123

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
