Answer:

14.86%

Step-by-step explanation:

The principal = $5800

Time = 5 years

Amount = $ 11600

From;

A= P(1 + r)^n

Substituting values;

11600=5800(1 + r)^5

Rate= (11600/5800)^1/5 - 1

Rate= 0.1486

Therefore

Rate= 14.86%

X + 5y = -27<br> -2x - 5y = 24
Rashid [163]

Answer:

Step-by-step explanation:

x+5y=-27

-2x-5y=24

If the signs are the same u minus if they are different u add

So they are different were gonna add

x+5y=-27

-2x-5y=24

-1=-3

You cant divide it further x=-3

Next were gonna subsitute in any equation

x(-3)+5y=-27

-3+5y=-27

+3 to -27

-7+3=-24

5y=24

24/5=4.8 y=4.8

I hope this helps.
