Answer:
x > 2
Step-by-step explanation:
-1/2x + 6 < 4x - 3
Start by adding 1/2x to both sides to get both x's on the same side
6 < 4 1/2x - 3
Add 3 to both sides to keep the x's by themselves on one side
9 < 4 1/2x
Divide both sides by 4 1/2 to get x by itself
2 < x so x > 2
1. given
2. addition property of equality
3. division property of equality
Answer:
<em><u>A chemist reacted 17.25 grams of sodium metal with an excess amount of chlorine gas. The chemical reaction that occurred is shown.</u></em>
<em><u>A chemist reacted 17.25 grams of sodium metal with an excess amount of chlorine gas. The chemical reaction that occurred is shown.__Na + __ Cl2 → __ NaCl</u></em>
<em><u>A chemist reacted 17.25 grams of sodium metal with an excess amount of chlorine gas. The chemical reaction that occurred is shown.__Na + __ Cl2 → __ NaClIf the percentage yield of the reaction is 88%, what is the actual yield? Show your work, including the use of stoichiometric calculations and conversion factors. </u></em>
ANSWER
The solution is
x=-3,y=-2
EXPLANATION
First equation
3x – 3y = –3
Second Equation:
5x – y = –13
Multiply the second equation by 3 to get:
Third equation:
15x-3y=-39
Subtract the first equation from the third equation:
Divide both sides by 12,
Put x=-3 into the first equation:
Group like terms,
The solution is
x=-3,y=-2
The answer would be True because the sequence is constant
