Answer:

10

Step-by-step explanation:

let a = amount of apple

let g = amount of grapefruit

14a+25g=340

a+g=2a-2

-a     -a

g=a-2

plug this into your first equation

14a+25(a-2)=340

14a+25a-50=340

              +50  +50

39a=390

a=10

you have 10 apples

lara31 [8.8K]

<em>The missing weights are:</em>

<em>2 2 2 1 11 12 12 2 24 22 24 3 37 22</em>

Answer:

Average = 12\frac{4}{7} \ lb

Step-by-step explanation:

Given

Weight of sea glass

To solve this question, we have to calculate the mean of the weight of the sea glass as follows;

Average = \frac{\sum x}{n}

Where n = number of sea glass

n = 14

So:

Average = \frac{\sum x}{n} becomes

Average = \frac{2 +2 + 2 + 1 + 11 +12 +12 +2 +24+22 +24 +3 +37+ 22}{14}

Average = \frac{176}{14}

Average = 12\frac{8}{14}

Simplify fraction

Average = 12\frac{4}{7}

<em>Hence; the weight of the sea glass would be </em>12\frac{4}{7}\ lb<em> </em><em>when evenly distributed...</em>
