Answer:
~1.29 inches
Step-by-step explanation:
C = 2πr
C = 3r + 4.25
2πr = 3r + 4.25
2πr - 3r = 4.25
r(2π-3) = 4.25
r = 4.25/(2π-3) ≈ 1.29
n=12
5/6n= 10
multiply both sides by 6.
5/6(6) n= 10(6)
5n=60
divide both sides by five and then you get 12.
Answer:
The solution to the system of equations is x=3 y= 23
Step-by-step explanation:
solving this system of equation using substitution method
-3x-y=14 ….. equation (1)
-9x =-27 ….. equation (2)
Solving for value of x from equation 2
-9x =-27
so x= -27/-9 = 3
so x = 3
The second equation is solved for x, so we can substitute the expression 3 in for x in the first equation (1)
-3x-y=14
-3 (3) - y =14
-9-y= 14
-9=14+y
y=-23
The solution to the system of equations is x=3 y= -23
We can check our work by plugging these numbers back into the original equations. Let's try -3x-y=14
-3x-y=14
-3(3) -(-23)= 14
-9+23 = 14
14= 14
Yes, our solution checks out.
Answer:
3
.75
the solved version would be .421875
the numbers on top are translated in English to .75 to the power of 3.
Step-by-step explanation:
I'm pretty sure this is correct
900+2,100=3000 that would be ur answer for that question
