Answer:

The answer is \frac{7}{3}

Step-by-step explanation:

In order to determine the answer, we have to express the statement to a algebraic expression.

The "two thirds" means \frac{2}{3}.

Then "plus a number" means +x. "x" is the variable that we want to know its value.

Then "plus 4" means +4.

So, the algebraic expression is:

\frac{2}{3}+x+4=7

Then, we have to solve for "x". We free this variable in any side of the equation:

x=-\frac{2}{3}+7-4\\x=\frac{-2+9}{3}\\x=\frac{7}{3}\\

Finally, the "x" value is \frac{7}{3}

2). Bill has twice as many candies as Fred. Tim has 3 fewer than 3 times as many candles as Fred.
sasho [114]

Step-by-step explanation:

<h2>Answer:-</h2>

\tt{Let \ the \ candies \ taken \ by \ Fred \ be \ x.}

Now, let's Solve!

So, according to Question,

Bill = 2x

Tim = 3x-3

Total Candies = 177.

\bf{x+2x+3x-3=177}

Totalling x,

\bf{6x-3=177}

\bf{6x=177+3}

\bf{6x = 180}

\boxed{\sf{x = 30}}

So, Fred has 30 candies.

Bill's Candies = 2×30 = 60 Candies

Tim's Candies = 3×30-3 = 90-3 = 87 Candies.

Hope it helps :)
