Asoftware company sells an education version (e) and a commercial version (c) of its popular image editing software. during the month of january 500 copies of the software are sold with sales totaling $180,000. if the price of the education version is $150 and the price of the commercial version is $600 how many of each version were sold?

The company sold nearly 267 educational version copies and nearly 233 commercial version copies.

Step-by-step explanation:

Let the education version software be = e

Let the commercial version software be = c

Equations forms:

      .......(1)

   ...... (2)

Multiplying (1) by 150 and subtracting from (2)

subtracting this from (2)

450c=105000

c = 233.33 rounding to 233

Then

e = 267

Hence, the company sold nearly 267 educational version copies and nearly 233 commercial version copies.

3; 9 is 8 to -4

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
