Without solving, the solution is greater than 21.  The can be proven because a fraction of x is equal to 21, therefore x cannot be less than 21.

Solving the linear equation

 \rightarrow\frac{x}{3}=21\\\\\text{Multiplying by 3 on both sides}\\\\\rightarrow\frac{x}{3} \times 3=21\times 3\\\\x=63

→63>21,

that is, solution of the linear equation is greater than 21.

Gina measured the amount of water her friends drink each day in gallons. The line plot shows the measurements.
vova2212 [387]

Line plots are used to represent data using lines and dots

The difference between the greatest amount of water and the least is 1/2

From the line plot (see attachment), we have the following parameters:

Least = 8\frac 28

Greatest = 8\frac 68

<h3>Calculating the difference</h3>

The difference (d) is then calculated as:

d =Greatest -Least

So, we have:

d =8\frac 68 -8\frac 28

Subtract the common terms (8)

d =\frac 68 -\frac 28

Take LCM

d =\frac {6-2}8

d =\frac {4}8

Reduce the fraction

d =\frac {1}2

Hence, the difference between the greatest amount of water and the least is 1/2

What is 2.75 rounded to the nearest hundredth
almond37 [142]
Well first off we need to know how to round or what rounding is. Rounding is the approximation of numbers usually decimals to a approximate cut off number for numbers that are too long or hard to work with/remember. To round a number you simply need to look at the number behind that number whether its a whole number (integer) or a decimal, either one will work. Now continuing on (on) how to round the number, look at the number after it and if it is 5 or above the number rounds up +1 and all numbers behind that turn to 0. For example 3.25500 round to the nearest hundredth, 3.26(000). Now if the number is 4 or smaller then you don't do anything at all (no rounding) and all the numbers after the being rounded number turn to 0's like so, 3.254(0000) rounded to the nearest hundredth, 3.25(00000). So now that we know how to round and what rounding is we need to look at are hundredth place on are number here and see what the next number is after that, in this case it is 0 because there is no stated number there the default next number is 0 like so,
2.750 and because 0 is under 5 we don't do any rounding at all here and just leave it as it is. So 2.75 rounded to the nearest hundredth is 2.75
