Answer:
36.666 (The six keeps going)
Step-by-step explanation:
In this question you'll be trying to find out what x is.
(x-8), this is from the amount of years ago and 2(56-x) is from subtracting 8 with 64 and the 2 came from the fact that Jeremy is twice the age.
(x-8)=2(56-x)
x-8=102-2x
Now we want to have x by itself so we'll add 2x on both sides to remove the -2x from the right side.
3x-8=102 (Add up on both sides)
3x=110 (Divide by 3)
x=36.666
Answer:
x = ⅘
Step-by-step explanation:
For clarity, exponents should be marked with a ^. 25x² can be written as 25x^2.
25x² = 16
divide both sides by the 25
x² = 16/25
take the square root of both sides
x = √(16/25) = √16/√25 = 4/5
