The concert lasts 60 minutes, and the songs are all the same length. the choir sings a total of 12 songs, 2 of which are sung by the sopranos only. for how many minutes do the sopranos sing by themselves? solve the equations using a letter for the unknown quantity.

10 minutes

Step-by-step explanation:

60 / 12 = 5

5 *2 = x=10

this means that x = 10

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )
