Answer:

2d = 58 (If you are just finding d then d = 29)

Step-by-step explanation:

69 + 53 = 122

180 - 122 = 58

Answer:

29

Step-by-step explanation:

The total degree of a triangle is 180 so

(69 + 53) + 2d= 180

122 + 2d= 180

2d= 180-122

2d= 58

Divide both side by 2

which 29

BUT

i dont really understand if the 2 was the multiple or it just "2d"

in that case "2d" would be 58.

Well first we know that 55.50 is 25% so I guess multiply it by 3 to get the full price equalling nearly 166 which is closest to 165, so that’d be my answer. Sorry if wrong.

Yuan makes punch by mixing cranberry juice and pineapple juice.
For every 3 cups of punch, he uses 2 cups of cranberry juice.

Drag the correct number of each type of juice into the box that would make 15 cups of Yuan's punch.

Answers

Answer:

Yuan would have 10 cups of cranberry juice and 5 cups of pineapple juice.

Step-by-step explanation:

For every 3 cups of punch, Yuan has 2 cups of cranberry juice. First, we need to find out how many "batches" of the punch Yuan is making. 3*5=15, so 5 batches. Then we have to find out how much cranberry juice they need. 2*5=10. Then, the pineapple juice. The pineapple juice is the rest of the punch, and 3-2=1. 1*5=5. To check, 10+5=15
