By seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.
We are given that a recipe for two people requires 1kg of rice to 150 g of meat.
That is the proportion of rice to meat is:
1 kg : 150 g
1000 g : 150 g
100 : 15
20 : 3
Now, we are also given that 1 kg that is 1000 g of dish is to be prepared.
Let the portion of rice in it be x.
Portion of meat = 1000 - x
ATQ:
20 : 3 :: x : 1000 - x
20 / 3 = x / (1000 - x)
20,000 - 20 x = 3x
23 x = 20,000
x = 20000 / 23 = 870 ( approx.)
1000 - x = 1000 - 870 = 130.
Therefore, by seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.

r = 5
Answer:
x = 10
Step-by-step explanation:
8x - 12 and 6x + 8 are corresponding angles and are congruent , then
8x - 12 = 6x + 8 (subtract 6x from both sides )
2x - 12 = 8 ( add 12 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
