So add all the numbers together (20 + 22 + 28 + 35 + 47 + 90) and you'll get 242. Then you take the number and divide it by the numbers in your set (you have 6 numbers so you'll divide by 6) 242/6. The answer would be 40.3333333 (repeating decimal). I hope this helps!
There is 6 sides in a cube, multiplying we get the number of squares:
6*10 = 60 little squares.
Peeling off one layer means subtracting 10 squares from the above numbers like this:
60 - 10 = 50.
Answer: we end up with 50 littles squares.
Answer:
-$407
-tax:6%
407 times 6 divided by 100
413/100
4.13
407 plus 4.13
$411.13
Answer:
Solve by substitution
[y=5/2x-4]
[y= -x+3]
Substitute y = -x +3
[-x+3=5/2x-4]
Isolate x for -x+3=5/2x-4: x=2
For y = -x+3
Substitute x = 2
y= -2+3
Simplify
y=1
The solutions to the system of equations are:
y=1 x=2
