Answer:
-5/8a - 2.8b
Step-by-step explanation:
-3/8a + 3.2b + (-6b) - 1/4a
=> -3/8a + 3.2b + (-6b) - 2/8a
=> -5/8a + 3.2b - 6b
=> -5/8a - 2.8b
Therefore, -5/8a - 2.8b is the solution to your problem.

Answer:
The amount of water need to be added is 5 liters.
Step-by-step explanation:
Let's "x" be amount of water in (liters) added to 15 liters of 40% of sugar syrup.
Now find the amount of sugar syrup = 40% of 15
= 0.4 × 15
The amount of sugar syrup = 6 Liters
To dilute 30% we need to find amount of water to be added.
So,
30% of (15 + x) = 6
0.3 × (15 + x) = 6
4.5 + 0.3x = 6
0.3x = 6 - 4.5
0.3x = 1.5
Dividing both sides, by 0.3, we get
x = 5
So, the amount of water need to be added is 5 liters.
A function is a relation that associates each element x of a set X, to a single element y of another set Y.
Circle is not a function of x. For x = 0 we have y = -7 and y = 7.
There are two cups in one pint and there are two pints in one quart. That means that there are four cups in one quart. Three cups would be 3/4 of a quart.
Hope that helped =)
