Call the amount of pineapple "P', and the amount of gingerale "G".

We know that a mix of pineapple and gingerale makes 200 cups. So: 
P+G=200

We also know that double the pineapple (i.e. 2P) and triple the gingerale (i.e. 3G) makes 420 cups. So:
2P+3G=420

We can now solve by substitution:
2P+3(200-P)=420
2P+600-3P=420
-P=-180
P=180

180+G=200
G=20

For 420 cups we need 2P=360 cups of pineapple and 3G=60 cups of gingerale]

Which inequality represents "six times a number is less than negative thirty-nine and three-quarters"?
jarptica [38.1K]

Answer:

6*n < - (39 + 3/4)

Step-by-step explanation:

Let's do it in steps:

"Six times a number" can be written as:

6*n

Where n is the "number"

"... is less than negative thirty-nine and three-quarters "

then we have:

6*n < - (39 + 3/4)

This is the inequality we wanted, now we can also solve this for n as:

n < -(39 + 3/4)/6

52 is 12.5 of what number
Ksenya-84 [330]
Well, 12.5 is 25/2.

\frac { 25 }{ 2 } \times n=52\\ \\ \frac { 2 }{ 25 } \times \frac { 25 }{ 2 } \times n=52\times \frac { 2 }{ 25 } \\ \\ \therefore \quad n=\frac { 104 }{ 25 } =\frac { 100 }{ 25 } +\frac { 4 }{ 25 } =4+\frac { 4 }{ 25 } \\ \\ \therefore \quad n=4.00+0.16=4.16
