If three quarters of a number decreased by twenty is equal to eighty two, what is that number?

Studentka2010 [4]

A number is :

$x$

_________________________________

Three quarters of it means :

$\frac{3}{4}x \\$

_________________________________

Decrease by 20 means :

$\frac{3}{4}x - 20 \\$

_________________________________

Equals to 82 means :

$\frac{3}{4}x - 20 = 82 \\$

_________________________________

What is that number ?

x asked so we must solve the above equation for x.

Let's do it....

$\frac{3}{4}x - 20 = 82 \\$

Plus sides 20

$\frac{3}{4}x = 82 + 20 \\$

$\frac{3}{4}x = 102 \\$

Multiply sides by 4

$3x = 102 \times 4$

Divided sides by 3

$x = \frac{102 \times 4}{3} \\$

$x = \frac{102}{3} \times 4 \\$

Simplify

$x = 34 \times 4$

$x = 136$

So that number is 136 .

Is it enough to plot two points to see a pattern for a graph ? Explain.

devlian [24]

No, the least amount of points you can do on a graph to see the pattern is 3 because than you can get a better line for your graph to see what kind of pattern your graph is.

How many 1/10s in 2 3/5

Umnica [9.8K]

It'd be clearer if you'd write: "How many tenths are there in 2 3/5?"

2 3/5 13/5

---------- = ---------- = 26

(1`/10) 1/10

There are 26 tenths in 2 3/5.
