Here’s why:
⸻⸻⸻⸻
- '9' is in the hundredths place. The rounding is the digit to it's right, or '3'.
- Since 3 is less than or equal to 4, we would round down.

Answer: 5
Step-by-step explanation:
The equation to solve this problem is 40 + 2x = 25 + 5x
Now, to solve for x you first need to subtract 25 from each side:
15 + 2x = 5x
Next, subtract 2x from each side:
15 = 3x
Finally, divide both sides by 3:
5 = x

Answer:
13 l of 15%, 13 l of 25%, 26 l of 70%
Step-by-step explanation:
solutions:
final solution:
This includes 0.45*52l= 23.4 l acid
Let's assume:
- amount of 15% solution= x
- amount of 25% solution= y
- amount of 70% solution= z
- and we have z=2y
so there are 2 equation:
or
- x+y+2y= 52 ⇒ x+3y= 52 ⇒ x= 52- 3y
- 0.15x+1.65y=23.4
- 0.15*(52-3y)+1.65y=23.4
- 7.8-0.45y+1.65y=23.4
- 1.2y=23.4-7.8
- 1.2y= 15.6
--------
- x= 52- 3*13= 13 l
- z= 2y= 2*13= 26 l
