WHO EVER ANSWERS FIRST GETS BRAINLIEST I REALLY NEED HELP!!! simplify... (3/8)^-2(1/3•3/8)^3(1/3)^4

i awnsered 4.2^(-3)*5.1^(2)*4.2^(4)*5.1^(3)

Step-by-step explanation:

14491.060542

4 adults and 12 babies

step-by-step explanation:

4 x 7 = 28

12 x 15 = 180

180 + 28 =208

4 x 3 = 12

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
