Answer:
3.5°
Step-by-step explanation:
Subtract 82 and 54, to find the total change in temperature, 28.
7:00 am and 3:00 pm are 8 hours apart, so divide 28 by 8.
Your answer should be D, 3.5° per hour.
Im pretty sure that the answer to your problem would be
4x^2-11x-3
40.00 for premium - 15.00 more than standard
40-15=35.00 for standard
Step-by-step explanation:
Given that,
a + 2b = 17
Also,
2a + b = 4
By adding the above expressions we get,
a + 2b + 2a + b = 17 + 4
3a + 3b = 21.
3 (a + b) = 21
a + b = 21/3
a + b = 7 Let us take 'b' = 10
a + 10 = 7
a = 7 - 10
a = -3
Now let's check by verifying by putting a = -3 and b = 10 in the previous expressions
a + 2b = 17
-3 + (2 × 10) = 17
-3 + 20 = 17
17 = 17
2a + b = 4
(2 × -3) + 10 = 4
-6 + 10 = 4
4 = 4
Therefore, a = -3 and b = 10 [(-3,10)] is the solution.
60+3=63
10x6+3=63
7x9=63
20x3+3=63
