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.

the correct answer is b) histograms can be used to exhibit the shape of distributions. this is because histograms count the frequency of each possible answer, so one is able to see which results are more common and which are less common.
