The line plot shows the number of bags of grapes,grouped by weight, to the nearest 1/8 pound. How many bags of grapes had a weig

Assoli18 [71]

Answer:

2.25 pounds

Step-by-step explanation:

The diagram showing the weight of bags with grapes is shown in the attached file below.

From the diagram; number of bags of grapes that had a weight of $\dfrac{3}{8}$ pounds or less is:

$\dfrac{3}{8}$ pounds = 3

$\dfrac{1}{4}$ pounds = 4

$\dfrac{1}{8}$ pounds = 1

Thus; the total is = 3+4+1 = 8

However, The total weight of the grapes in the bag that had a weight of $\dfrac{3}{8}$ pounds or less is :

= $\dfrac{3}{8}(3) + \dfrac{1}{4}(4) + \dfrac{1}{8}(1)$

= $\dfrac{9}{8} + 1 + \dfrac{1}{8}$

= $\dfrac{9+8+1}{8}$

= $\dfrac{18}{8}$

= 2.25 pounds

Answer: $\bold{C)\ -\dfrac{1}{2}}$

Step-by-step explanation:

$.\qquad \dfrac{x+2}{15}=\dfrac{x+1}{5}\\\\\\\rightarrow (15)\dfrac{x+2}{15}=\dfrac{x+1}{5}(15)\\\\\\\rightarrow x+2=3(x+1)\\\\\rightarrow x+2=3x+3\\\\\rightarrow \qquad 2=2x+3\\\\\rightarrow \qquad -1=2x\\\\\rightarrow \qquad -\dfrac{1}{2}=x$
