The cost to rent a rug-cleaning machine from the supermarket is $23 per day. the supermarket charges a check-out fee of $45 for the rental. tristanne spent $137 to rent the rug-cleaning machine. if d represents the number of days tristanne rents the machine, which equation can be used to find the value of d?

d represents the number of days Tristanne rents the machine

the rent is $23 per day, so for "d" days its 23d

check out fee is $45

total amount is $137

forming an equation

137=45+23d

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
