6.1 1 a) and b) let x be a string of length n, and let y be a string of length n − k, for 1 ≤ k < n. we wish to line up the symbols in x with the symbols in y by adding k blanks to y. a) suppose that we decide to add the k blanks in one continuous block. how many ways are there to do this? b) suppose that we add two separate blocks of blanks, one of size i and one of size k − i, for 1 ≤ i < k. how many ways are there to do this?

step-by-step explanation:

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
