82% if you put it as a decimal it would be 0.82.
Answer:
Jack is 31
Lacy is 10
Step-by-step explanation:
x - 9 = 22
since jack is 3 times as old as lacy,
the formula is
3x - 9 = 22
3x = 31
x = 10.3
So Jack is 31
And Lacy is 10
To prove this, subract 9 (years) from both ages
It will give you an approximate sum of 22 years for both their ages, as the question states
Since Lacy is a little over 10 years old, Jack is 31 instead of 30
The formula was taken from someone elses answer so sorry if it`s wrong
Finding equivalent ratios and finding equivalent fractions are basically the same thing. You need to divide the numerator and denominator
Step-by-step explanation:
Let a=x+2 and b=x+6
The area of a rectangle is given by
A=a*b
So
![(x + 2) \times (x + 6) = {x}^{2} + 8x + 12](https://tex.z-dn.net/?f=%28x%20%2B%202%29%20%5Ctimes%20%28x%20%2B%206%29%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20%2B%208x%20%2B%2012)
