The answer to this equation is 1/2
A. 12*x + 2*y = 90
6*x + 2*y = 60
To write system of equation you just need to sum all solo and ensemble acts and make it equal to how much they will last for.
B. Here we can multiply second equation with negative 1 and add it to first equation.
6x = 30
x = 5
now we replace x in any of 2 equations to get y.
30+2y = 60
2y = 30
y=15
Solo acts are 5 minutes long and ensemble acts are 15 minutes long
Answer:
<u><em>3544.392</em></u>
Step-by-step explanation:
The value of the total number of population is P=2000The value of the rate of interest isR%=4.5%The value of the time is T=13yrs
For compounded annually
n=1
The expression for the final value of the population after
13years is,A=2000(1+4.5100)13=3544.392
if you can give me brainliest that would be great
