Answer:
5/12 inches per minute
Step-by-step explanation:
If A snail crawls 5/8 inches in 3/4 minute, then;
5/8 inches = 3/4 minute
we are to fine the distance covered in a minute;
x inches = 1 minute
Divide both expressions
5/8x = 3/4
24x = 20
12x = 5
x = 5/12
Hence the snail covered 5/12 inches per minute
Answer:
A = 20.25π sq meters
Step-by-step explanation:
C = 2πr
9π = 2πr
divide π from each side to get:
9 = 2r
r = 9/2 or 4 1/2
A = πr²
A = π (4.5²)
A = 20.25π
Answer:
Step-by-step explanation:
hello :
a(x) = 3x - 12 and b(x) = x-9, so
a[b(x)]=a(x-9) =3(x-9)-12
a[b(x)]=3x-9-12
a[b(x)]=3x+21
Answer:
7-x
This is because 7 itself is decreased by a number, if for e.g that number was 5, the expression would mean 7-5= 2
