5n + (-6) = -2
add 6 to -2
5n = -2 + 6
5n = 4
divide both sides by 5
n = 4/5

Let' call the number 'M' for 'mystery number'.

The number . . . . .  M

Five times the number . . .  5 M

The sum of 5 times the number and  -6 . . .  5 M - 6

You said that's  -2 .  So I can write

                                         5 M - 6  =  -2

Add  6  to each side:      5 M       =   4

Divide each side by  5 :     M       =  4/5   or   0.8  .

Suppose that you have $6,000 to invest. Which investment yields the greater return over a 10 year period: 7.44% compounded daily
Nikitich [7]
Hi
Here is you answer mate
But don’t forget to mark me the brainliest


Plug the applicable numbers into the compound interest formula and see which is more.
A = p(1+r/n)nt
A = future amount
p =principal investment
r = interest rate as a decimal
n = number times compounded per year
t = time in years

A = 5000(1+.0743/365)365(10)
= 5000(1.000203562)3650 = $10,510.38

A = 5000(1+.075/4)4(10)
= 5000(1.01875)40 = $10,511.75

As you can see these are practically equal, but the 7.5% quarterly is more.

Given x less than y, compare the following expressions and determine which is greater: 2x-y;2y-x. Explain your answer
sweet [91]

Let's form the difference of the two expressions and see what we can learn.

(2y -x) -(2x -y) = 2y -x -2x +y = 3y -3x = 3(y -x)

Since y > x, this is positive, so 2y -x is greater than 2x -y.
