Answer: 455 / 7
Step-by-step explanation: Three answer choices have the same quotient as 4.55 ÷ 0.7. Which one does NOT?
answer choices
455 ÷ 70
455 ÷ 7
45.5 ÷ 7
4.55 ÷ 0.70
The number resulting from the division of one number by another is regarded as quotient. For example, The quotient of 12 divided by 4 is 3.
And so, the first, third and last options on expansion by division all yield the same results in decimals (6.5) as that in the question (4.55 / 0.7 = 6.5) which is an indication that they have the same quotient.
Only the second option does not do so. 455 / 70 = 65

Answer:
i think its c but im not 100 percent sure.
Step-by-step explanation:
Part (a)
Let's replace x with 15 and evaluate to see if he is correct or not.
x/2 - 3 = 6
15/2 - 3 = 6
7.5 - 3 = 6
4.5 = 6
We get a false statement after simplifying everything. We need to get the same number on both sides to get a true statement. Therefore, Ahmed is not correct.
<h3>Answer: No, he is not correct</h3>
===============================================
Part (b)
Let's solve for x. We do so by first adding 3 to both sides, and then multiplying both sides by 2. This follows PEMDAS in reverse, undoing everything to isolate the variable.
x/2 - 3 = 6
x/2 = 6+3 .... add 3 to both sides
x/2 = 9
x = 9*2 .... multiply both sides by 2
x = 18 is the answer
As a check, we'll use the same idea as part (a)
x/2 - 3 = 6
18/2 - 3 = 6
9 - 3 = 6
6 = 6
We get a true statement this time. This confirms x = 18
<h3>Answer: x = 18</h3>
