Is 0.3x (4 - y) and - 1.2x - 0.3y equivalent

Mathematics

Answer:

Inconsistent

Step-by-step explanation:

We are given the equations;

0.3y=0.6x+0.3

1.2x+0.6=0.6y

Assuming we are required  to determine whether the system of equations are consistent or inconsistent  

We are going to use substitution

Making y the subject;

Equation 1: 0.3y=0.6x+0.3

Dividing both sides by 0.3

y = 2x + 1

Equation 2: 1.2x+0.6=0.6y

Dividing both sides by 0.6

y = 2x + 1

This means both equations are similar and we can't get a solution.

Therefore, the system of equations is inconsistent.

Lewis fills his thermos with 2 liter of water. Garret fill his thermos with 1 of water. How many more milliliter of water does l
cluponka [151]

For this case we have to:

Lewis carries 2 liters of water

Garret carries 1 liter of water

So, Lewis has 1 liter of water more than Garret.

By definition we have that 1 liter equals 1000 milliliters.

Thus, Lewis carries 1000 milliliters more water than Garret.

Answer:

1000 milliliters

Saline solution A is 10% strength and saline solution B is 5% strength. I have an order for 6 litres of an 8% saline solution. T
kupik [55]
Let x = volume of saline solution A,
y = volume of saline solution B.

We're going to set up two equations. 
Firstly, x + y = 6. That gives us y = 6 – x     (1)

Second, 0.1x + 0.05y = 0.08•6, 
or 0.1x + 0.05y = 0.48               (2)

Substitute (1) into (2):
0.1x + 0.05(6 – x) = 0.48
0.1x + 0.3 – 0.05x = 0.48
0.05x + 0.3 = 0.48

Subtract 0.3 from both sides:
0.05x = 0.18
x = 3.6
Then y = 6 – 3.6 = 2.4

So we have to use 3.6 litres of solution A and 2.4 litres of solution B.
