3xy -6x
just multiply 3x by y and 3x by -2
1st question
$23,760-(4000+6000)=$13,760
$13,760 x 4%=$ 550.40
2nd question
$43,300-(2000+2000)= $39,300
$39,300 x 5%= $1,965
Answer:
YET
Step-by-step explanation:
TO DECRYPT DKA USING THE CAESAR SHIFT CIPHER STARTING WITH 5 SHIFTS.
TO DO THIS DECRYPTION, WE'RE GOING TO LOOP THE ALPHABETS.
D = LOOPING THIS LETTER 5 TIMES, WE HAVE C - B - A - Z - Y.
SO, D IS DECRYPTED AS Y
GOING FURTHER, THE ENCRYPTION SHIFTS BY AN ADDITIONAL SPACE. THIS MEANS, IF THE FIRST "Y" WAS ENCRYPTED IN 5 SPACES TO GET D, AND AN ADDITIONAL SPACE WAS ADDED TO THE NEXT ALPHABET, IT BECOMES 6.
K IS THEN DECRYPTED AS
K = J - I - H - G - F - E
K IS DECRPYTED AS E
GOING FURTHER, THE NEXT WAS ENCRYPTED WITH AN ADDITIONAL SPACE EVEN MORE, SO, A IS DECRPYTED AS
A = Z - Y - X - W - V - U - T.
THUS, DKA IS DECRYPTED AS YET
It’s -7
7-(-4) is 7+4, which is 11
3 times -6 is -18
11 + -18 is -7
Answer: 15/4 or 3 3/4
Explanation: You make 2 1/2 into 5/2 (improper fraction) and 1 1/2 into 3/2.
You multiply the two together (5/2 x 3/2) equaling 15/4 (improper fraction) or 3 3/4 (mixed fraction)
