givi [52]

Answer: If the recipe wants 3/4 cup of pineapple juice for every 6/4 cups of orange juice, 18/4 is 6x more than the recipe so 6/4 must be 6x larger too.

6 x 3/2 = 18/2 or 9 cups of orange juice. Hope this helps :) Please mark brainliest if you can ;)

Factor the expression<br> 20g3 + 24g2 – 15g – 18
abruzzese [7]
First, put parenthesis around the first two numbers and the last two numbers. 
(20g³+24g²) (-15g-18)
Then, take out the greatest common factor of both parenthesis. 
4g²(5g+6)-3(5g+6)
You then separate the numbers outside the parenthesis and the numbers in the parenthesis. 
(5g+6) (4g²-3) 
Then you simplify the second set of numbers. Since the set of numbers can't be simplified, you would leave this problem as it is. I hope this makes sense.

Solve for n.<br> 4 x n= 21.6
Kay [80]

Answer:

n = 5.4

Step-by-step explanation:

Equation:  4n = 21.6

To solve this equation for n, divide both sides by 4 to get n by itself.

<u />

<u>Step 1:  Divide both sides by 4</u>

4 * n / 4 = 21.6 / 4

n = 5.4

Answer:  n = 5.4
