Answer:
1 Kilogram is $1.44
Step-by-step explanation:
$2.88 divided by 2 kilograms is $1.44 for each kilogram of sand.
About 49 pounds
$5.75 x 2 = 11.50
561.60 / 11.50 = 48.83 (round)
49 lbs
Median is described as the number in the middle of the set (given that the set is ordered from least to greatest), so we'll first order our set.
[48 49 50 52 54 62]
We notice that there is no middle number, so we take the two numbers that share the middle space and find their mean.
50+52=102
102/2=51
The median is 51.

Answer:
(12, -23)
Step-by-step explanation:
to find x, substitute the value of y into y
-2x+1=-3x+13
collecting like terms
-2x+3x=13-1
x=12
to find y substitute the value x=12 into any of the equation
y=-3x+13
y=-3(12) +13
y= -36+13
y=-23
Answer:
To solve, use a simple one-step equation
Known: Number of coins; Number of Nickles.
Unknown: Number of Dimes.
a) To find the number of Dimes
b) Use x (or virtually any letter) to represent the unknown number of dimes
c) 9+x=13
d) Subtract 9 from both sides to cancel out the 9 and isolate the variable on one side. x=4
e) 9+4=13, so yes, the answer is correct
