We know that a positive number where only one and itself divide it is called a prime number. A positive number with divisors other than 1 and itself are called composite numbers.
Answer:
(9, 6)
Step-by-step explanation:
add equations together: (x + y = 15) + (x - y = 3) --> x + x + y - y = 15 + 3 --> 2x = 18
isolate the variable: 2x/2 = 18/2 --> x = 9, so the x-coordinate is 9
substitute 9 in x's place in one of the equations: 9 + y = 15
solve for y: y = 15 - 9 --> y = 6, so the y-coordinate is 6
combine x and y coordinates together: (9, 6)
Im pretty sure the answer is A
2×8=16 bring down the 6 carry the one 2×1=2+1=3 so you have 36
bring down a 0 3×8=24 carry the 2 bring down the 4 3×1=3+2=5 which is 540
540+36=576
the answer is 576
