<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
5x(3 - 12x) - 3(4 - 20x²)
<u>Step 2: Simplify</u>
- Distribute: 15x - 60x² - 12 + 60x²
- Combine like terms: 15x - 12
Answer:
10%
Step-by-step explanation:
24 R + 16 Blu + 10 Y + 22 G + 8 Bla = 80 total
Then you cant set up a proportion:
In order for 80 to become 100, you must multiply it by 1.25. That means in order to get X, the probability of pulling a black marble, you can multiple 8 x 1.25
8 x 1.25 = 10
Answer: Length = 9 in
Width = 12 in
Step-by-step explanation:
Length L = 3 + W
Perimeter P = 42 in
Perimeter = 2L + 2W
plugin values:
42 = 2(3 + W) + 2W
42 = 6 + 2W + 2W
42-6 = 4W
W = 36 / 4
W = 9
solve L by substituting the value of W=9 into the equation:
L = 3 + W
L = 3 + 9
L = 12
therefore, the dimensions of the rectangle:
Length = 9 in
Width = 12 in
9 and then 4 for every 9 goldfish, there are 4 gallons of water
