Students played dodgeball and volleyball for 45 min. they played dodgeball for 11 more minuets than volleyball. how long did they play dodgeball

28 minutes

Step-by-step explanation:

d + v = 45

d = v + 11

time to sub

(v + 11) + v = 45

2v + 11 = 45

2v = 45 - 11

2v = 34

v = 34/2

v = 17 minutesvolleyball

d = v + 11

d = 17 + 11

d = 28 minutes <=== dodge ball

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

sine
