Answer:
987 ft.
Step-by-step explanation:
We can solve this with an equation.
Since she has 5 rolls of 99 feet long blue streamer, then she has 5*99=495 feet of blue streamer
Since she has 9 rolls of 88 feet long blue green, then she has 9*88=792 feet of blue green
To find the total, we can add them up and get 495+792=987
Answer:
327,310
Step-by-step explanation:
<span>"Y is inversely proportional to the cube of x" translates to Y = kx</span>³ where k is unknown constant. We need to solve for k.
So we have Y = 3 and x = 2. Plug in and we get 3 = k2³ = 8k
So k = 3/8
Now we can solve for Y when x = 3
Y = (3/8)3³ = (3/8)27 = 81 / 8
Final answer: 81 / 8
The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.
If you were to solve the equation it would look like this:
2x+6=3x-8
-3x -3x
-x+6=-8
-6 -6
-x=-14
/-1 /-1
x=14
10%of30=3
3x4=12
