Area = Length x Height
Area = 5.4 x 5.4
Area = 29.16
Answer:
<h3>#1</h3>
<u>Rectangle area:</u>
<u>Given:</u>
<u>Find w:</u>
- 12w = 300
- w = 300/12
- w = 25 ft
<h3>#2</h3>
<u>Perimeter is the sum of side lengths:</u>
P = 2 1/4 + 5 2/5 + 5 17/20 =
2 + 5 + 5 + 1/4 + 2/5 + 17/20 =
12 + 5/20 + 8/20 + 17/20 =
12 + 30/20 =
12 + 1.5 =
13.5 ft
<h3>
#3</h3>
- Cost of a shirt = $19.99
- Number of shirts = 6
<u>Total cost:</u>
-3.0625 is the answer to x

Answer: n - 10 which is choice C</h3>
Let's use an example. If Nathaniel earned $15 on Tuesday, and earned $10 less on Wednesday, then 15-10 = 5 dollars is the amount he earns on Wednesday.
Now let's say he earned $27 on Tuesday, and still earned $10 less the next day, meaning that he earns 27-10 = 17
Whatever he earns on Tuesday, subtract off 10. That's the rule to follow for this problem.
(amount earned on Tuesday) - 10 = amount earned on Wednesday
If n reprsesent the placeholder for "amount earned on Tuesday", then we can rewrite that equation as
amount earned on Wednesday = n - 10
In short, whatever 'n' is, subtract 10 off it. In the examples above, I used n = 15 and n = 27.
note: the order of subtraction matters. The expression n-10 is not the same as 10 - n. If you subtract in the wrong order you may get a negative value (eg: 10 - 17 = -7), but he can't earn a negative amount of dollars.
Hello from MrBillDoesMath!
Answer:
Leftmost graph: x<= -2 or ( minus infinity, -2]
Middle graph: (-5, infinity)
Right graph: (-2, 3)

I
n the graphs the white circle means that value is NOT included in the set. For example, In the Right graph the values -2 and +3 (the "endpoints") are NOT included in the solution set.
In graphs ")" means the value is NOT included but "]" (the square bracket) means the value IS included.
