why are the solutions to the proportions - 20 and 60 - the same?
because both result in the equation 20x=500, which simplifies to x - 25
because both result in the equation 20x=500, which simplifies to - 250
because both result in the equation 10x= 1,000 which simplifies to x 10
because both result in the equation 10x=100,which simplifies to x
100

because both result in the equation 10x= 1,000 which simplifies to x = 10

Step-by-step explanation:

Given the question:

Why are the solutions to the proportions 50/x=10/20 and 10/50=20/x the same?

The solution of each proportion is:

50/x=10/20

50*20 = 10*x

1000 = 10*x

1000/10 = x

x = 100

10/50=20/x

10*x = 50*20

10*x = 1000

x = 1000/10

x = 100

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

days of the week

step-by-step explanation:

javier earned more money then kyle, so that won't always be a constant term, but the days of the week do not change so that term is always constant.
