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.
Answer:
the difference between, minus, decreased by
Answer:
2(5x - 3)
Step-by-step explanation:
Given that:
=(7x-5)-(-3x+1)
Now by simplifying:
"-" sign before the bracket will alter inner signs
= 7x - 5 + 3x - 1
Adding same terms:
= 10x -6
By taking 2 common:
= 2(5x - 3)
