If you take 2/5 minus 8/10 the final results would be -2/5 and it equals -0.4.
Change in temperature = final - initial
= 22 - (-13)
= 22 + 13
= 35
In short, Your Answer would be 35
Hope this helps!

Arithmetic is additive and geometric is multiplicative, and the numbers aren''t multiplying, they're adding.
Answer:
Credit remaining after 21 minutes = $30.4
Step-by-step explanation:
Credit remaining on a phone card is a linear function of the total calling time.
When graphed, let the linear function representing the line is,
y = mx + b
Where 'm' = slope of the line
b = y-intercept
From the graph,
Slope of the line = -0.12
y = -0.12x + b
If this line passes through a point (33, 28.96),
28.96 = -0.12(33) + b
b = 28.96 + 3.96
b = 32.92
Therefore, the linear function is,
f(x) = -0.12x + 32.92
where x = calling time
Credit left in the card after 21 minutes,
f(21) = -0.12(21) + 32.92
= -2.52 + 32.92
= $30.4
Answer:
Y = 6
X = 10
