Answer:
B. 10 1/2 feet
Step-by-step explanation:
We are told that she taped 7 boxes.
We are also told that she uses 1 1/2 feet of tape to close each box.
Therefore, the length of tape she will need to use for the 7 boxes will be the product of 7 boxes and 1 1/2 feet of tape per box:
L = 1 1/2 * 7 = 3/2 * 7 = 21/2 = 10 1/2 feet.
She will need to use 10 1/2 feet of tape.
Answer: yes, she did made an error, a very big mistake.
Step-by-step explanation:
first, we have varieties of ways in which we can use to solve this, the most important thing is to stick to the mathematical rules of solving any equations.
using the most simpler method
-4x + 11 = 6x + 1
collect like ter
-4x -6x = 1 - 11
-10x = -10
divide bothside by -10
-10x/-10 = -10/-10
x=1
secondly, using the method she is intending to use, its more easier to subtract 6x from bothside
-4x + 11 = 6x +1
-6x -6x
_______________
-10x + 11 = 1
-10x = 1-11
-10x = -10
x = 1
or still we can doing it exactly as she did, but it will take us through a long way i.e by adding +6
-4x + 11 = 6x + 1
+6x +6x
_______________
2x +11 = 12x +1
2x-12x = 1-11
-10x=-10
x=1
Answer:
<u><em>Yes, No, Yes, Yes, Yes!</em></u>
Step-by-step explanation:
First Question:
<u>That is correct </u>because if you have $0 in your bank account and you withdraw $30 you will have -$30!
(And you are in debt which everyone hates!)
Second Question:
<u>No</u>, because that would be 125 above ground. You would need to say -125 instead of adding.
Third Question:
<u>Yes!</u> Let's say in the football game you had 70 yards, subtracting the 15 yards which you supposedly had lost would result in 55 yards therefore proving the fact that you did not progress but did the exact opposite!
Fourth Question:
<u>Yes</u>, because you are gaining more on your stock. This results in you getting more of a share in a company or product.
Fifth Question:
To be honest, I don't know if this: "0 feet could represent the altitude of a city that is located at sea level." is a question but I will answer it nonetheless!
<u>Yes,</u> because before right where the sea "starts" is what is called point 0. Meaning that, you are located at sea level!
