Answer: k = 5°
Step-by-step explanation:
- A triangle adds up to 180°. Therefore, the equation is 115 + (4k + 5) + (6k + 10) = 180.
- Remove the parenthesis and combine the like terms. 115 + 5 + 10 = 130 and 4k + 6k = 10k. The equation simplifies to 130 + 10k = 180.
- Subtract 130 on both sides. 10k = 50
- Divide by 10 on both sides. k = 5
The answer is: Substitution property of equality.
The explanation is shown below:
1. To solve this problem you must apply the proccedure shown below:
2. When you clear the variable x from the first equation, and subtitute it into the second equation, you obtain:
<span>3x−2y=10
x=(10+2y)/3
4x−3y=14
</span>4[(10+2y)/]−3y=14
<span> y=-2
3. When you subsitute y=-2 into the first equation and clear the x, you have:
x=2

It's the water
The salt would be the solute that dissolves in the solvent.
Temp - is a factor
(affecting rate at which salt dissolves)
grams - unit of measure

Let me walk you through this real quick:
-4x + 9 (10x - 1)
-4x + 90x - 9 (open up the brackets)
90x - 4x - 9
= 86x - 9
