Tickets to a festival cost $7.00 each, and lunch costs $13.00 per person. renting a bus to and from the festival costs $63.00. which expression gives the cost of x people going to the festival?

20x+63

Step-by-step explanation:

add all of the multiplying factors which increase at the same rate, in this case it is 7.00 a ticket and 13.00 for food per person, making it 20.00 per person. Then place your variable next to that to signal the solver they are multiplying them, finally adding the 63.00 because they only need one bus and it isn't multiplying by the number of people.

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
