Answer:
9d^2/(2d + 4).
Step-by-step explanation:
18d^2 / (4d + 8)
First factorise the denominator:
= 18d^2 / 4(d + 2)
The GCF of 18 and 4 is 2 so this simplifies to:
9d^2/2(d + 2)
= 9d^2/(2d+ 4).
Step-by-step explanation:
20≤F≤80
20=9/5c+32
-12=9/5c
-60=9c
-6.7=c
80=9/5c+32
48=9/5c
240=9c
26.7=c
-6.7≤C≤26.7
2.89
This is 289% as a decimal.
100%s are 1s, so
200% = 2
Answer:
2.5 inches per hour
Step-by-step explanation:
divide the total by time
6 1/4
--------= 5/2
2 1/2
simplify 5/2 to 2.5
