i think it A
Step-by-step explanation:
Answer:
l = P/2 -w
Step-by-step explanation:
P=2(l+w)
Divide each side by 2
P/2 = 2(l+w)/2
P/2 = l+w
Subtract w from each side
P/2 -w = l+w-w
P/2 -w =l
72 + 12x = 24 + 24x

Answer:
warmer by 30.2 degrees
Step-by-step explanation:
It might help to think of these values plotted on a number line. Both temperatures will be left of zero, with -63°C being farther to the left (colder).
The difference can be found by subtracting the colder temperature from the warmer one:
-32.8 -(-63) = -32.8 +63 = 63 -32.8 = 30.2 . . . degrees
The South America temperature -32.8°C is 30.2° warmer than the North America temperature.
Answer:
y = 3
Step-by-step explanation:
4y + 3 = 15 First subtract 3 from each side.
4y + 3 - 3 = 15 - 3 The 3 on the left will cancel.
4y = 15 - 3
4y = 12 Divide each side by 4
4y/4 = 12/4 The 4 on the left will cancel because 4/4 = 1
y = 12/4
y = 3
