Answer:

Step-by-step explanation:
Given the initial ratio of 3 parts water to 5 parts fruit juice, you can set up a proportion (equivalent ratios) to determine the amount of water needed with just 1 part of fruit juice:

cross multiply: 5x = 3
divide: 5x/5 = 3/5 or x = 3/5
3/5 = 0.6 parts water
Answer:
They both have area 4
Step-by-step explanation:
Area of the square:

Area of the triangle:
Using the left-side of the triangle as the base, and the height from the left-side to the bottom-right corner:


We know the length of the diagonal is
as we are using a centimetre grid, so we can create an isosceles triangle with side lengths 1 and our unknown length, we can then use Pythagorean Theorem to work out our unknown side length.




X= a number
The opposite of a number is its negative opposite. It's the additive inverses of a number. The additive inverse of 4 is -4. It will always equal zero when added together.
Inequality:
1/3(-x) < 12
