Isabel has 10 boards that are x meters long. She has
5 boards that are 2x meters long. She also has 4
boards that measure 3 meters, 6 meters, 9 meters,
and 13 meters, respectively. If she were to lay all
her boards in a straight line with no gaps between
them, the boards would measure 271 meters.
What is the value of x ?
E. 5 meters
F. 6 meters
G. 10 meters
H. 12 meters

H. 12 meters

Step-by-step explanation:

Hi, to answer this question we have to sum all the boards’ lengths. That expression must be equal to 271.

Mathematically speaking:

10x +5 (2x) +3+6+9+13=271

Solving for x:

10x +10x +3+6+9+13 =271

20x+31 =271

20x = 271-31

20x =240

x =240/20

x =12

Feel free to ask for more if needed or if you did not understand something.

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
