Perimeter: 36
5n + 3 = 36
5 · 6.6 + 3 = 36
N = 6.6
------------------------------------------
Perimeter: 36
1/4n + 2 = 36
1/4 · 136 + 2 = 36
N = 136
Hopefully i understood the question correctly :) Hope this helps
Answer:t= 9
Step-by-step explanation: 10t =90
divide 10 on both sides
so 10t /10 and 90/10
which means t=9
A = P + I
2a = a + PTR/100
2a = a + 5aT/100
2a = a(1+T/20)
2=1+T/20
T=20 yrs
Answer:
multiple choice is worth 2
short response is worth 4
Step-by-step explanation:
23x + 10y = 86
28x + 5y = 76
solve by elimination
multiply the top by -1 and the bottom by 2
-23x + -10y = -86
56x + 10y = 152
add them
33x = 66
x = 2
with x = 2 plug x into one of the equations
23x + 10y = 86
23(2) + 10y = 86
46 + 10y = 86
10y = 40
y = 4
x = 2 and y = 4 so
multiple choice is worth 2
short response is worth 4
The difference would be subtracting the variables and the dividing the difference by 2
