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.
That is false because you can’t do anything if the variables are not the same.
Answer:
20
Step-by-step explanation:
This is the formula for a combination. Substitute the values and evaluate the expression.
Answer:m=754 r=644
Step-by-step explanation:
m+r=1398
m=r+110 m-r=110
Combining both equations
m+r=1398
m-r=110
Add both equations
m+m+r-r=1398+110
2m=1508
Divide both sides by 2
2m/2=1508/2
m=754
Substitute m=754 in m+r=1398
754+r=1398
r=1398-754
r=644
