If you add 21 to my number and then multiply the result by 3, you will get 84 more than two-thirds of my number. Find my number.

Ksivusya [100]

Based on the calculations, the unknown number is equal to $\frac{-45}{7}$

Let the unknown number be x.

<h3>How to find an unknown number:</h3>

Translate the word problem into an algebraic expression, we have;

Adding 21 to the unknown number:

$21 +x$

Multiplying the result by 3:

$3\times (21+x)$

84 more than two-thirds of the unknown number:

$\frac{2x}{3} +84$

Equating the equations, we have:

$3\times (21+x) = \frac{2x}{3} +84\\\\43+3x=\frac{2x}{3} +84$

Cross-multiplying, we have:

$43+3x=\frac{2x}{3} +84\\\\129+9x=2x+84\\\\9x-2x=84-129\\\\7x=-45\\\\x=\frac{-45}{7}$

In a game, the probability of winning is 1 out of 5. How many times could Lisa expect to win if she plays the game 85 times?

Murrr4er [49]

Answer:

17 wins

Step-by-step explanation:

Given

P(winning) = 1/5

Number of games = 85

The number of winnings could simply be calculated as the product of the probability and number of games played.

Expected number of winning : P(winning) * number of games

Expected number of winning = 1/5 * 85 = 17 wins
