Answer:
$1.95
Step-by-step explanation:
notebook = n
pencil = p
3n + 2p = 5.10
2n + 3p = 4.65
multiply top equation by 2 and bottom by 3
6n + 4p = 10.20
6n +9p = 13.95
subtract bottom equation from the top equation
-5p = -3.75
divide by 5, negatives cancel out
p = 0.75
sub p into either equation, I chose the original top equation
3n + 2(0.75) = 5.10
3n + 1.50 = 5.10
subtract 1.50 from both sides
3n = 3.60
divide both sides by 3
n = 1.20
p = 0.75
n + p = 1.95 (the fourth option)
It is very simple the answer is 12.7 cm
You can simply multiply 5 with 2.54 to get the answer
Hope it helps : )
Answer:
6 and 3
Step-by-step explanation:
place 325 on top and line up 52 with 25 on bottom. Then multiply 2 with 5 to get 10. Place the zero bellow the line and carry the 1 over the 2. Multiply 2 times 2 to get 4 and then add one to get 5. Put the five bellow the line. Multiply 3 times 2 to get a total of 6 and bring it bellow the line. Bring a zero bellow the 0 that's bellow the line. Multiply 5 times 5 to get 25. Bring the 5 to the left of the zero you just placed and carry the 2. Multiply 5 times 2 to get 10 and add the 12. Place the 2 to the left of the 5 you just placed bellow the line and carry the 1. Multiply 5 times 3 to get 15 and add the 1 to get 16. Place the 16 to the left of the 2 you just placed bellow the line. Then add 650 plus 16250 to get an answer of 16,900.
Wow that was long and hard to explain LOL. :)
