Jane’s favorite fruit punch consists of pear, pineapple, and plum juices in the ratio 5: 2: 3.
chapter reference

how much punch can she make if she has only 6 cups of plum juice?

20cups

Step-by-step explanation:

If Jane’s favorite fruit punch consists of pear, pineapple, and plum juices and are divided in the ratio 5:2:3, the total mixture will be addition of all the ratio which gives;

5+2+3 = 10

If she had only 6cups of plum juice, the total cups of juice made can be calculated as shown;

3/10 × x = 6 where x is the total cup of juices she made.

Note that the ratio of the plum juice was divided by the total in the calculation since that's the only data given.

From the equation above;

3/10 × x = 6

3x/10 = 6

cross multiplying

3x = 60

x = 60/3

x = 20

Therefore the total punch made by her was 20cups

entering that problem on the tube might get you an answer

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
