Answer:

4 and 5

Step-by-step explanation:

n + 1 > 4

n > 4 - 1

n > 3

For the set { 1, 2 , 3 , 4, 5 }, 4 and 5 are greater than 3.

Hence, 4 and 5 makes the inequality n + 1 > 4 true.

Can somebody please balance this !?!
Lera25 [3.4K]
\mathrm{CO}_2 has 2 oxygens for every carbon. \mathrm{CO} will contribute one of each for every molecule. You then have to have an even multiple of \mathrm{CO} molecules to not end up with an odd number of oxygens.

So if you take 2\mathrm{CO}, you should end up with 2 carbons on the RHS. 2\mathrm{CO}_2 then has 4 oxygens. 2 of them are already accounted for, so you just need one \mathrm O_2 to balance out the reaction.

1\mathrm O_2+2\mathrm{CO}\Rightarrow2\mathrm{CO}_2

5-2(4a+1)+3a=13 <br><br> A= 2/3<br> A= -2<br> A= -6/5<br> A=2
VMariaS [17]

Answer:

                   a = -2

Simplifying 5 + -2(4a + 1) + 3a = 13 Reorder the terms: 5 + -2(1 + 4a) + 3a = 13 5 + (1 * -2 + 4a * -2) + 3a = 13 5 + (-2 + -8a) + 3a = 13 Combine like terms: 5 + -2 = 3 3 + -8a + 3a = 13 Combine like terms: -8a + 3a = -5a 3 + -5a = 13 Solving 3 + -5a = 13 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -5a = 13 + -3 Combine like terms: 3 + -3 = 0 0 + -5a = 13 + -3 -5a = 13 + -3 Combine like terms: 13 + -3 = 10 -5a = 10 Divide each side by '-5'. a = -2
