Operations with variables can give you excluded values by making the denominator equal to zero.

Ex. 48/60 always equals to 4/5 but 4x/6x is not always equal to 2/3 because when you make x equal to zero it makes the equation invalid.

Increase 840 in the ratio 2 : 3

Iteru [2.4K]

Ratios be 2x and 3x

$\\ \rm\longmapsto 2x+3x=840$

$\\ \rm\longmapsto 5x=840$

$\\ \rm\longmapsto x=\dfrac{840}{5}$

$\\ \rm\longmapsto x=168$

Now

2x=2(168)=336
3x=3(168)=508

Sam wants to find the best buy on cans of tuna. He reads these four ads in the newspaper.$12.53 for seven cans$5.97 for three ca

grandymaker [24]

In each case divide the price by the number of cans.
The best buy is the lowest price.
$12.53/7 = $1.79
$5.97/3 = $1.99
$7.95/5 = $1.59
$8.34/6 = $1.39

The fourth ad, $8.34 for 6 cans results in the lowest price per can, $1.39.
The fourth ad is the best buy.

Can I get help with this?

Answer:

y-4=7(x-1)

Step-by-step explanation:

Hi there!

We are given the slope of the line (7) and the point (1,4) and we need to find the equation in point-slope form.

Point-slope form is given as y- $y_{1}$ =m(x- $x_{1}$ ) where m is the slope and ( $x_{1}$ , $y_{1}$ ) is a point

We have all of the needed information for the equation, but let's first label the values of everything in order to avoid confusion

m=7

$x_{1}$ =1

$y_{1}$ =4

now substitute into the formula:

Hope this helps! :)
