Answer:
Last option is the correct choice.
Step-by-step explanation:
Convert the mixed numbers into fraction and apply the rate formula.
Rate = Change / Unit Time
= 12 1/4 ÷ 3 1/2
= 49/4 ÷ 7/2 (Answer matching with the last option)
= 49/4 x 2/7 (Inverting the second fraction)
= 7/2
= 3 1/2
The rate of change per hour is 3 and a half degrees in temperature.

Answer:
0
Step-by-step explanation:
5(2x + 2) = 10
10x + 10 = 10
10x = 0
x = 0
Using the volume of the rectangular prism, it is found that the three dispensers will take 1,344 in³ in Sid's refrigerator.
<h3>What is the volume of a rectangular prism?
</h3>
The volume of a rectangular prism of length l, width w and height h is given by the multiplication of these three dimensions, that is:
V = lwh.
In this problem, there are three dispensers, each with l = 4 in, h = 14 in, w = 8 in, hence the volume is given by:
V = 3 x 4 x 14 x 8 = 1,344 in³.

2 - 3d = 4d - 19
Add the opposite to both sides to get the variable on the left side only.
2 - 3d = 4d - 19
-4d -4d
2 - 7d = - 19
Then get the terms w/o variables on the right,
2 - 7d = - 19
-2 -2
-7d = -21
Then divide by the number paired with the variable.
--7d = -21
----- ----- ; d = 3
-7 -7
Final answer = 3
Hope I helped :)

reverse the numbers when given a ratio similar to this one. 6x7=42 and 7x6=42 so x is 6 y is 7
