Answer:
4
Step-by-step explanation:
because y is 90 and x is 20 so z is 71
Answer:
x=3, y=9
Step-by-step explanation:
5x-2y=-3
4x-2y=-6
Then:
solve for y:
-2y=-6-4x
y=3+2x
Substitute y into either equation:
4x-2(3+2x)=-6
4x-6-4x=-6
-6=-6, use other equation
5x-2(3+2x)=-3
5x-6-4x=-3
x-6=-3
x=3
then:
y=3+2(3)
y=9
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
