The equation that can be used to find the coldest temperature recorded in Siberia is y + 10 = -80
Let the coldest temperature in Alaska be x
The coldest temperature recorded in Alaska was –80°F
x = –80°F
Let the coldest temperature in Siberia be y
The coldest temperature recorded in Alaska was 10°F warmer than the coldest temperature recorded in Siberia
This can be interpreted as:
Coldest temperature in Alaska = Coldest temperature in Siberia + 10
x = y + 10................(*)
Since x = -80
Substitute x = -80 into equation (*)
-80 = y + 10
This can be re-written as:
y + 10 = -80
The equation that can be used to find the coldest temperature recorded in Siberia is y + 10 = -80

X = 27.5
8x = 220, so 220/8 = 27.5
Answer:
415people
Step-by-step explanation:
20%of250=100people
15%of the 100people=15people
So 100 went out remaining(500-100)400
Then 15 returned=400+15
<u>4</u><u>1</u><u>5</u>
If you draw the figure, RT and SQ turn out to be the diagonals of the rectangle since diagonals of a rectangle are equal, so RT = SQ ==> 4x - 16 = x + 5 ==> 4x - x = 5 + 16 ==> x = 21/3 = 7
