Note: (2/3) yard= (2/3)(3 ft) = 2 feet
Ans: 2/6 = 1/3 foot
Each piece is 1/3 foot long
Pi=3.14. X=(3.14+3)/2. X=6.14/2. X=3.07 :)
Answer:
11x + 8
Step-by-step explanation:
You can do this by counting the like terms that have the same variable (x)
2x + 4x + x + 4x = 11x
3 + 5 = 8
Answer is 3x
Reduce the index of the radical and exponent with 2
<u><em>subsitution</em></u> means subsituteing something for another and getting the answer
the way to do this is to get an easy equation and make it equal to only one placeholder so
y=2x
so you can subsitute y for 2x anywhere you see a y
3x+y=5
subsitutute
3x+2x=5
5x=5
divide both sides by 5
x=1
subsitute
y=2(1)
y=2
<u><em>elimination</em></u> is when you elimintate one of the terms by adding the equations together and canceling som of them out
so y=2x
subtract y from both sides
0=2x-y or 2x-y=0
add this to the second equation
3x+2x+y-y=0+5
5x=5
divide both sides by 5
x=1
subsitute
y=2(1)
y=2
x=1
y=2
