If a team of workers can assemble 12 computers per hour, how many computers can they assemble in four hours?

answer: they can assemble 48 computers in four hours.

step-by-step explanation:

given: the number of computers assembled by team in one hour= 12

to find the number of computers assembled in four hours, we use unitary method and multiply 12 by 4 , we get

the number of computers assembled in four hours =

i.e. the number of computers assembled in four hours = 48

hence, they can assemble 48 computers in four hours.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality
