X - ( 1 / 2 )x - ( 1 / 3)x = 6x / 6 - 3x / 6 - 2x / 6 = ( 1 / 6 )x, where x is full tank of gas
The answer is 1 / 6 of the gas have left ;
<span>'x' can be anything. There's no information here to say that it must be
one thing or another. You can't find 'x', because there is no
equation.
You can probably simplify the fraction by doing some factoring, but
there's
no way to tell a value for 'x'. As long as 'x' is not -4, it can be anything, and
its value determines the value of the fraction.</span>
Answer: 40
Step-by-step explanation:
Given
Jar contains 200 old dimes
Chances to pick the 1960s is 20% i.e. 1960s is 20% of 200 old dimes
So, we can write
![\Rightarrow \text{No of 1960s is }=20\%\ \text{of}\ 200=0.2\times 200\\\Rightarrow \text{No of 1960s is }=40](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctext%7BNo%20of%201960s%20is%20%7D%3D20%5C%25%5C%20%5Ctext%7Bof%7D%5C%20200%3D0.2%5Ctimes%20200%5C%5C%5CRightarrow%20%5Ctext%7BNo%20of%201960s%20is%20%7D%3D40)
Cos (314) = .694 is positive
