Distribution property
a(b+c) = ab*ac

A store's profit P varies directly with the number of items n that they purchase from a warehouse. Greg's gadgets buys 75 Wacky
vovangra [49]

Answer:

P=-2.54n.

Step-by-step explanation:

We have been given that a store's profit P varies directly with the number of items n that they purchase from a warehouse.

We know that two proportional quantities are in form y=kx, where y is directly proportional to x ad k is constant of variation.

Upon substituting our given variables, we will get:

P=kn

We are also told that Greg's gadgets buys 75 Wacky Widgets from Gadget Supply Warehouse. The store's profit for this purchase is -190.50. Let us find constant of proportionality.

-190.50=k\cdot 75

\frac{-190.50}{75}=\frac{k\cdot 75}{75}

k=-2.54

Therefore, our required equation would be P=-2.54n.

The first step to solve the equation StartFraction x over 4 EndFraction minus three-fourths = 16 is shown below. StartFraction x
artcher [175]

Answer:

Addition property of equality

Step-by-step explanation:

The given expression is :

\dfrac{x}{4}-\dfrac{3}{4}=16

We need to find the first step to solve this expression.

For this, we add 3/4 to both sides of the equation i.e.

\dfrac{x}{4}-\dfrac{3}{4}+\dfrac{3}{4}=16+\dfrac{3}{4}\\\\\dfrac{x}{4}=16+\dfrac{3}{4}

So, we have used the addition property of equality.
