2 1/4 x 1 1/2
= 9/4 x 3/2
= 27/8
= 3 3/8
Zero is like a negative number. It is mathematically impossible to subtract across zeros
Answer:
r=3
Step-by-step explanation:
24π=2π(r^2+r)
Divide each side by 2 pi
24π/2π =2π/2π(r^2+r)
12 = r^2 +r
Subtract 12 from each side
12-12 = r^2 +r -12
0 = r^2 +r -12
Factor
What number multiply to -12 and add to 1
4*-3 = -12
4-3 = 1
0= (r+4) (r-3)
Using the zero product property
r+4 =0 r-3 =0
r+4-4 =0-4 r-3+3=0+3
r = -4 r = -3
Assuming r is the radius, r must be positive
r =3
Answer:
$2.22 i think
Step-by-step explanation:
Answer:
x<-3 or x>-1
Step by step explanation:
Start with -5x>15. To get x by itself, we have to divide each side by -5. When we do that we get x<-3. (Don't forget to flip the sign when dealing with negative · and ÷.) Now answer the second equation. x-5>-6 To get x by itself, add 5 to both sides to get x>-1. Now we have x<3 or x>-1.
