Answer:
T-shirts cost $20; each pair of pants cost $12.
Step-by-step explanation:
x is T-shirts ; y is each pair of pants
(8x+5y=220) -1
(5x+y=112) 5
----------------------
-8-5y=220
25+5y=560
----------------
17x=340
x=20
<span>
-- "Two hundred and three thousandths"
means' ' 2.003 '.
-- "Two hundred three thousandths" would mean ' 0.203 '.
How can you tell the difference?
The difference is the 'and'.</span> "And" means 'decimal point'.
' 678 ' is read as "six hundred seventy eight", with no 'and'.
' 40.06 ' is read as 'forty and six hundredths'.
' 0.46 ' is read as ' forty-six hundredths'.
Answer:
The value of this new equation would be (2x - 5)/6x.
Step-by-step explanation:
In order to find the value of this equation, we need to take the original equation and replace every x with (x - 1/x+2).
f(x)= 3x - 1/4x + 2
f(x)= [3(x - 1/x+2) - 1]/[4(x - 1/x+2) + 2]
f(x) = [(3x - 3/x + 2) - (x + 2/x + 2)]/[(4x - 4/x + 2) + (2x + 4/x + 2)]
f(x) = (2x - 5/x+2)/(6x/x + 2)
f(x) = (2x - 5)/6x
