Answer:
Brother is 70.5 and sister is 64.5
Step-by-step explanation:
you will need to set up a simple equation and give out variables.
Girls age = 6-x
Brother's age= x
the you will take those 2 and add them and place them equal to 135:
6-x+x=135
6-2x+6=135+6
The 6 cancels out
2x=141
2x/2=141/2
x=70.5
The brother's age would be 70.5 then and the girl's would be 64.5
8 x/3 apply the formula x power/root. Hope that helped!
You have to rearrange into the format y=mx+b.
Answer: 255 sq meters
Step-by-step explanation:
C = 2(pi)r
C=Circumference=20 Meters
Pi = 3.14 and r is the radius
So, 20=3.14*r
r=20/3.14=6.36942675
Area = 2(pi)r^2
2*3.14*(6.36942675)^2
254.77707
Round to nearest whole number
A=255 sq meters
