Answer:

x = 63, y = 27

Step-by-step explanation:

x and 117 are adjacent angles and sum to 180°

x + 117 = 180 ( subtract 117 from 180 )

x = 63

x and y sum to 90°

x + y = 90

63 + y = 90 ( subtract 63 from both sides )

y = 27

(2 Fruit juice A is composed of 2 parts apple juice and 1 part grape juice.
Elenna [48]

The amount of kilograms of each type of original fruit juice weighs; 12 kg of Apple and 6 kg of grape

<h3>How to Solve Algebra Word Problems?</h3>

The concentrations of apple and grape juice in the two different juice types are given as;

Juice A:

(2/3) apple

(1/3) grape

Juice B:

(1/3) apple

(2/3) grape

Let a be how much juice A is in the mixture;

Let b be how much juice B is in the mix.

Thus;

²/₃a + ¹/₃b = 10     ------(eq 1)

¹/₃a + ²/₃b = 8       ------(eq 2)

Solving both equations simultaneously gives us;

a = 12 and b = 6

Thus, the amount of kilograms of each type of original fruit juice weighs; 12 kg of Apple and 6 kg of grape
