Answer:
There are 7 Pigs and 6 Chickens
Step-by-step explanation:
Let's assume
Pigs= x
Chicken=y
(eq 1) x+y = 13----------y=13-x
4x + 2y = 40
replace the y
4x+ 2(13-x) = 40
you get x = 7
replace x in y=13 -x
you get y = 6
hence the answer.
Answer;
= $ 3623.85
Explanation;
To calculate compound interest we use the formula;
FV = OV( 1 + r/100)^n
FV=Future value which is what the value will be after the interest is calculated, this is what you are looking for.
OV=Original value, the amount of money you started with, in this case
3000
r=interest rate, in this case its 6.5
n=years its being compounded annually, in this case 3
= 3000(1 + 6.5/100)^3
= 3623.848875
≈ 3623.85

Answer:
x = 10
Step-by-step explanation:
Given
+ 13 = 
( multiply through by 10, the LCM of 5 and 2 to clear the fractions )
2x + 130 = 15x ( subtract 2x from both sides )
130 = 13x ( divide both sides by 13 )
10 = x
