1/2 is another word for .5 or 50 percent. But if you Multiply 1/2 by 2, you multiply and you'll get 2/2 which reduces down to 1.
Answer:
L = 80.2 + 2(0.4)
(b) No, one linear equation will be sufficient to solve the problem. Because it is not two statements of equation
Step-by-step explanation:
Between 1996 and 2005, there is 10 years difference.
It is given in the question that the life expectancy increases by 0.4 every five years.
Between 1996 and 2005, life expectancy of woman born will increase by 2x0.4 = 0.8.,
In 2005, the life expectancy of woman born is:
L = 80.2 + 0.8 = 81.0 years
If x + y = 5 and 3x = 2 then what you
do is:
3x = 2 and since you want the variable by itself you’d divide by 3... giving you an answer of x = 2/3 BUT YOURE NOT DONE YET
so now you plug what x equals (2/3) into the equation x + y = 5:
2/3 + y = 5
to solve this you have to subtract each side by 2/3 so x = 5 - 2/3
(5/1 - 2/3.... to get like denominators multiply the nominator and the denominator for 5/1 by 3 giving you: 15/3 - 2/3 = 13/3)
your final answer would be 13/3
Answer:
This is because modulus number will be always positive
Hope this is correct and helpful
HAVE A GOOD DAY!
