Not sure if I’m understanding this wrong but for x you can multiply the top equation by -3 to get -12x-15y=-21 and the bottom by 4 to get 12x-8y=-48.
For y you can multiply the top equation by 2 to get 8x+10y=14 and the bottom equation by 5 to get 15x-10y=-60
The answer would be 243 because 9 x 20 is 180 and 9 x 7 is 63 so 180+63 is 243
Answer:
50% is water
Step-by-step explanation:
1. 80% is water and 20% is from other material
2. Lets say a fruit has 100g, to make it easier to understand
2. if the fruit loses 75% of its water, it will lose 75% of 80%, which is 60% of the total weight or 60g lost. The fruit is now 40g
3. If 20% was other material (20g), now other material is 50% (the same 20g)
4. Water is now only 20g, which is 50% of the total weight
