Answer:
4.45935
Step-by-step explanation:
<span>there are 100 centimeters in a meter.
therefore 2.5 meters = 2.5 * 100 = 250 centimeters.
x = the length of the first board.
2x + 18 = the length of the second board.
x - 12 = the length of the third board.
x + 4 = the length of the fourth board.
the total length of all the boards is equal to 5x + 10,
since the total length of the board is 250 centimeters, then you get:
5x + 10 = 250
</span><span>solve for x to get x = 48 centimeters.
the 4 board lengths are:
x = 48
2x + 18 = 114
x - 12 = 36
x + 4 = 52
add them up and you get a total of 250 centimeters.
250 centimeters / 100 = 2.5 meters.
this confirms the solution is good.

Answer:
The equation 31=2c-7 to determine the number of points Carlos scored in the last game.
Step-by-step explanation:
We are given with,(I think every number is repeating for 3 times. So, I took each number as once)
Fabio had 7 less than 2 times as many points as Carlos. And Fabio score 31 points.
Let Carlos scored in the last game as "C".
So, we can set up equation for Fabio had 7 less than 2 times Carlos as
Fabio= 2C-7
Like so for Fabio score 31 as
Fabio =31
So, substitute Fabio as 31 into the first equation, we get
31= 2c-7
So, the equation 31=2c-7 to determine the number of points Carlos scored in the last game.
