Need asap! write the missing base. 256 + (power 6 with the missing base) 16 = (power 4 with missing base) will give brainliest! read carefully. you ^^

256 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2

       = 2⁸

16 = 2 * 2 * 2 * 2

   = 2⁴

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

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
