Answer:

A) P = 240

B) P + Po = 1040

C) P = 270.58

D) P+Po = 1070.58

E) Option B (compound interest) is better, as it generates more interest for the same inicial value, rate of interest and time

Step-by-step explanation:

The formula for simple interest is:

P = Po*r*t

Where P is the interest earned, Po is the inicial value, r is the rate of interest and t is the time.

The formula for compound interest is:

P+Po = Po*(1+r)^t

So we have that:

A) P = 800*0.06*5 = 240

B) P + Po = 800 + 240 = 1040

C) P+Po = 800*(1+0.06)^5 = 1070.58 -> P = 1070.58 - 800 = 270.58

D) P+Po = 1070.58

E) Option B (compound interest) is better, as it generates more interest for the same inicial value, rate of interest and time

Please need help on this one
Nookie1986 [14]
The answer is 130°
Because it is a circle, the angles have to all add up to 360°. So if you add up the two known angles, and subtract that sum from 360, you will get 130°

5x + 4 = 9 + 5(x - 1)​
Wittaler [7]

Answer:

All real numbers are solutions!

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+4=9+5(x−1)

Step 1: Simplify both sides of the equation.

5x+4=9+5(x−1)

5x+4=9+(5)(x)+(5)(−1)(Distribute)

5x+4=9+5x+−5

5x+4=(5x)+(9+−5)(Combine Like Terms)

5x+4=5x+4

5x+4=5x+4

Step 2: Subtract 5x from both sides.

5x+4−5x=5x+4−5x

4=4

Step 3: Subtract 4 from both sides.

4−4=4−4

0=0
