The school band sold T-shirts to raise money for an upcoming trip. it sold 120 shirts, which was 30 percent of the total sales on sunday. How many T-shirts did the band sell in all?

Let the total T-shirts be x : then,

30 % of x = 120

(30/100)x = 120

x = 400

The band sell 400 T-shirts in all

Step-by-step explanation:

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:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
