Answer:

N=6

Step-by-step explanation:

First, you move the -15 to the other side along with -9 so you have like terms in the same side. This will make it easier for you to solve for the answer.

To move -15 to the other side, you simply move it over next to -9 and change the sign. Since it was -15, it becomes positive 15. So the equation should look like n= -9 + 15.

Now, the equation looks much easier, right? All you need to do to find the answer is do -9+15, which equals 6. That's it!

a) 3(-2) + 4(3) = -6 + 12 = 6

b) 2(-2) -3(3) +5 = -4 -9 + 5 = -8

c) 4(-2) -(3) = -8 -3 = -11

d) -(-2) -2(3) = 4 -6 = -2

e) (1/2)(-2) +(3) = -1 +3 = 2

f) (2/3)(3) -(1/2)(-2) = 2 + 1 = 3

A high-interest savings account pays 5.5% interest compounded annually. If $300 is deposited initially and again at the first of

inessss [21]

That is an annuity and use the attached formula.

Total = 300 * [(1.055)^11 -1] / .055 -300
Total = 300 * 1.8020924036 -1 /.055 -300
Total = 300 * .8020924036 / .055 - 300
Total = 300 * 14.5834982473 -300
Total = 4375.0494741818 -300
Total = 4075.05
