<span>PV=NRT</span>If you want to solve that for n, remember that you can multiply or divide the whole equation by any number or expression as long as you do it to both sides. For example, if we divide both sides by R we get
<span><span><span>PVR</span></span>=NRT</span>or<span><span><span>PVR</span></span>=NT</span>after canceling R from both numerator and denominator on the right. Continue the process to solve for N.
All we need to do to find the answer is to multiply 1/2 by 7:
1/2 * 7 =
= 7/2 =
= 3 1/2

Answer:
4x+5 = 2x-9
Step-by-step explanation:
Answer:
- solution to both: 2, 4
- solution to inequality only: -2, 4.25, 3 1/4
- not a solution: 9 1/2
Step-by-step explanation:
Using x for the variable, the inequality will be ...
9.50 +3.50x ≤ 35
3.50x ≤ 25.50
x ≤ 51/7 ≈ 7.3
Anna cannot buy negative snacks, and she cannot buy fractional snacks. Of the numbers listed, only 2 and 4 are integers between 0 and 7 (inclusive). The values below 7.3 are all solutions to the inequality. The value 9 1/2 is too large to be a solution to the inequality.
Only 2 and 4 are solutions to both the problem and the inequality.
9 1/2 is not a solution.
