Can anyone help me with the 7th and 8th question which I have taken a bad photo of?
1 answer:
<u>Question 7: Define x : </u> Let the digit in the ones place be x. The digit in the tens place is x+2. The sum of the digit and its reverse is 66 <u>Find x:</u> 10(x + 2) + x + 10x + (x + 2) = 66 10x + 20 + x + 10x + x + 2 = 66 22x + 22 = 66 22x = 44 x = 2 <u>Find the number:</u> The number in the ones place = x= 2 The number in the tens place = x = 2 + 2 = 4Answer : The number is 42 . <u>Question 8:</u> <u>Define x:</u> Let the digit in the tens place be x. The digit in the ones place is x+7. The number = 10x + x + 7 = 11x + 7 If the digit interchange, the number = 10(x + 7) + x = 10x + 70 + x = 11x + 70 <u>Find x: </u> 9(11x + 7) = 2(11x + 70) 99x + 63 = 22x + 140 99x - 22x = 140 - 63 77x = 77 x = 1 <u>Find the number: </u> x = 1 x + 7 = 1 + 7 = 8 So the number is 18Answer: The number is 18.

The numbers that have a negative sign in front of them come first because they are less than 0. The other numbers can be ordered by what comes first. For example, 3 is bigger than 1 so 3 would come after 1.
I believe the answer is the second one I am in the same class.
Answer:
80%
Step-by-step explanation:
Percentile rank = (number of scores lower or equal to 82 / total number of scores) * 100%
Percentile = (8 / 10) * 100%
= 0.8 * 100%
= 80%
