375-3x=y

y=the amount of money left after buying x pieces of wood

So, we were given 2 variables, x and y. The amount of money that Margot has saved up, $375, and the cost of each piece of wood, $3.

So, if Margot buys x pieces of wood, it would cost her 3x (3 times x) dollars, and to find the remaining money, simply subtract what she had earlier to it. So the equation will be.

y = 375-3x

Hope this helps!

x-y+z=

x = 5
y = 3
z = 9

(5) - (3) + (9) =

Which of the following numbers can be expressed as repeating decimals? 3 over 7, 2 over 5, 3 over 4, 2 over 9

Maurinko [17]

Hello!

Let's think about the denominators we have. A seventh goes on forever in no specified order. A fifth an a fourth have set decimal values, 0.2 and 0.25, so they are not repeating decimals. A ninth is 0.111111..., it repeats like this forever in a specified order. Therefore, 2/9, or 0.222222...., would be a repeating decimal.

Therefore, our answer is $\boxed {\frac{2}{9}}$ .
