After a power failure, the temperature in a freezer Increased at an average rate of 3.5 °F per hour. The total Increase was 24.5 °F. Enter and solve an equation to find the number of hours until the power was restored. Let x represent the number of hours it takes for the temperature to increase to 24.5 °F.
The equation to find the number of hours until the power was restored is ____x = _____
The number of hours until the power was restored is ______ hours.
<Please fill in the blanks I will give you brainliest if you answer correctly>
Answer:
3.5x=24.5
3.5x7=24.5
X=7
Step-by-step explanation:
3.5 times what equals 24.5
3.5x1=3.5
3.5x2=7
3.5x3=10.5
Keep doing this and increase the number you are multiplying 3.5 by until your answer is 24.5.

Step-by-step explanation:
Answer and Step-by-step explanation:
1) No. 5m and 3a do not have any common factors.
2) Yes. They have a common factor of 2. So, it could be combined as 2(2 + 2y).
3) Yes. They have a common factor of 2x. So, it could be combined as 2x(4 - 1).
4). Yes. They have a common factor of 5. So, it could be combined as 5(3 + 2).
5). Yes. They have a common factor of t². So, it could be combined as t²(7 + 9t³).
6. Yes. They have a common factor of 3. So, it could be combined as 3(y³ + x⁶).

Use substitution to find the ordered pair of the following system of equations:
y=6x
y=5x+7
(_,_)
Answer:
first substitute 'y' in 2nd equation by right side of 1st one and you get:
now substract 5x from both sides of 2nd equal and you get:
as a result of the equal above you get:
now substitute x in very first equation by the result from above (x=7):

Question Help;
Sheldon can read 8 pages in 15 minutes. Amy can read 16 pages in 1 hour. Explain how you could use a table or graph to find how much longer it would take Amy to read a 320-page book than Sheldon.
Answer:
First you must convert time to the same units.
8pages/15min= 32pages/1 hr
now you can clearly see the ratio
Amy: 16/hr
Sheldon: 32/hr
We can see that Sheldon reads twice as fast as Amy.
This should be a good starting point, sorry I don't have much time to finish this question. Hope this helps good luck!

20 points each!!! Heather has 2 less than 5 times the amount of shoes that Donna has, Gina has 1 more than 2 times
amount of shoes that Donna has. Let x represents how many shoe Donna has.
a. Write an expression that represents how many more pairs of shoes Heather has than Gina.
b. Simplify the expression:
c. How many more pairs of shoes does Heather have is Donna has 14 pairs of shoes?
Answer:
A. (5x - 2) - (2x +1)
B. x -1
C. 68
Step-by-step explanation:
Heather = 5 times Donna -2 H = 5D - 2
Gina = 2 times Donna + 1 G = 2D + 1
Plug in D for X and you get
H = 5x -2
G = 2x + 1
If Heather's expression is 5x -2 and Gina's expression is 2x + 1 then to show how many more Heather has than Gina. You have to subtract Gina from Heather.
(5x - 2) - (2x +1)
Now to simplify it, you just combine all the like terms.
5x - 2 - 2x -1 = 3x - 3 and then you can simply this further by dividing all terms by 3. x - 1
To solve how many Heather has if Donna has 14. You substitute 14 for x in Heather's equation. 5 (14) -2 = 70 - 2 = 68
