Answer:
53+54+55+56
Step-by-step explanation:
I don't remember equation but I know this is the because I can roughly estimate the numbers by dividing by four and going from there
I’m not sure what the rule would be in this context, but those are just the squares of decreasing numbers starting at 10. It’s 10^2, then 9^2, then 8^2, and so on.
Answer:
c=10
Step-by-step explanation:
pythagreom theroem
c (hypotenuse) = 
plug in values for a and b
c=
c=
c=
c=10
M=-1/2 because you do y1-y2 over x1-x2 and end up with 2/-4 but simplified is -1/2
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)
