The price, e, of an entertainment system at extreme electronics is $220 less than twice the price, u, of the same system at ultra electronics. the difference in price between the system at extreme electronics and ultra electronics is $175.which system of linear equations can be used to determine the price of the system at each store?

The price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.

Step-by-step explanation:

Let the price of the system at the ultra electronics be u

Let the price of the system at extreme electronics be e

According to question, we have

Now, using the substitution method, we will solve the above system of equations.

Now, put the value of u in the first equation :

Now, we put the value of u in the equation which is given by:

Hence, the price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.

5x+10 is the correct one

hope this

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
