Complete the table for the given rule.
Vesna [10]

The values of x and y are:

x       y

2       1

5       2.5

7       3.5

Step-by-step explanation:

Given rule for function is:

y = \frac{x}{2}

As in the table,, we are given the values of y, which means we have to find x.

So,

y = \frac{x}{2}\\x = 2y\\

so

for y = 1

x = 2(1) \\x = 2

For y = 2.5

x = 2 (2.5)\\x = 5

For y = 3.5

x = 2(3.5)\\x = 7

so,

The values of x and y are:

x       y

2       1

5       2.5

7       3.5

Water makes up about 60% of the average adult's body weight. Represent this percent by shading in the squares.
Viefleur [7K]

Answer:

shading three boxes

Step-by-step explanation:

It is given that :

The body weight of an average adult = 60%

We have to show this by shading the square boxes shown.

There are 5 square boxes in total which makes up 100%.

So divide 100 by 5, we can 20% for each box.

So, 20% + 20% + 20%  will give us 60%

Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.

This is represented by the figure below.
