Answer:

there's no solution.

Step-by-step explanation:

if y = 3x -4 then use this instead of y in the second equation

9x -3(3x+4) = 14 ➡9x-9x -12 = 14 9x will eliminate -9x and -12 can't be = 14 so there's no solution

Serial numbers for a product are to be made using 2 letters followed by 3 digits. The letters are to be taken from the first 6 l

<h3>Answer: 21600 </h3>

==========================================================

Explanation:

There are 6 letters to pick from {A,B,C,D,E,F} and we have two slots to fill, where no repeats are allowed. This means we have 6*5 = 30 different ways to pick two letters.

There are 10 digits to pick from {0,1,2,...,9} and there are 3 slots to fill. This gives 10*9*8 = 720 different permutations for this portion.

Overall, we have 30*720 = 21600 different serial numbers possible.

omeli [17]

Answer: 7.5

Form your proportion. Let x be the width of QRST.

Length of ABCD Length of QRST
----------------------- = -------------------------
Width of ABCD Width of QRST

8/5 = 12/x

Solve for x by cross-multiplying.
(8)(x) = (12)(5)
8x = 60
x = 7.5
