4000000+500000+8000+200+20+7
Okay so lets call Leah "L" and her cousin "C". We know that L+C=36 ... we also know that Leah is twice her cousins age. Therefore, L=2 times C, or L=2C. This is because Leah's age is equivalent to twice as much as her cousin's.
Now that you know that L=2C, you can plug this back into the equation. This should make it so that's there's only one variable now!
L+C=36
(2C)+C=36 ... here we subbed in L=2C
3C=36 ... we add up the C's
C=12 ... we isolate for C by dividing both sides by 3
So her cousin's age is 12 years old. Leah's age is twice that. Thus, she's 24. If you add the two up: 12+24, you indeed get 36. Hope that helps :))

Answer:
18 Hours
Step-by-step explanation:
$330 - $60
= $270
$270 / $15
= 18 Hours
Hope this Helps! :)
So let's begin!
So the length is 25 and the entire perimeter is 106. Lets put these both of these numbers as information we know.
We know the length is 25.
We know the full perimeter is 106.
We also know a rectangle has 2 pairs of congruent sides.
Okay so, the length is 25.
Since there are two sides that are the same we would multiply 25 by 2 to get 50.
Now we know 2 sides out of the four sides on a rectangle.
106 is the final perimeter, if we subtract 50 from 106, we get 56. That is the measurement for both sides we're missing but we need to know the width for just one side.
So we divide 56 by 2 to get 28.
The width is 28.
Heres the show your work part:
25 x 2 = 50
Gets both lengths for rectangle.
106 - 50 = 56
Gets the product for the widths.
56 / 2 = 28
Gets the width of just one side.
Your final answer: 28
