========
Ratio of 8th graders to 7th graders = 3 : 2
Let the number of graders be 3x and 2x
Number of 8th graders = 18
So , 3x = 18
x = 18/3 = 6
Number of 7th graders = 2 × 6 = 12
Ratio of 6th graders to 7th graders = 5 : 4
Let the number of graders be 5a and 4a
Number of 7th graders = 12
So , 4a = 12
a = 12/4 = 3
Number of 6th graders = 5×3 = 15 ANS

Answer:
yes
if you solve the equation,
5x+15=7x-11
26=2x
x=26/2=13
Step-by-step explanation:
The digit in the hundreds place has a value 10 times as great as the value in the tens place. The digit in the tens place has 1/10 the value of the digit in the hundred place
<h3>What is place value?</h3>
Place value is simply the value of each digit in a number.
For instance:
- The 3 in 350 represents 3 hundreds, or 300
- The 5 in 5,006 represents 5 thousands, or 5,000.
It is important to note that place value is the value represented by a digit in a number on the basis of its position in the number or figure.
We can deduce the following:
- The digit in the hundreds place has a value 10 times as great as the value in the tens place
- The place value of a digit at the hundredths place is 1/10 times the same digit at the tenths place
Thus, the digit in the hundreds place has a value 10 times as great as the value in the tens place. The digit in the tens place has 1/10 the value of the digit in the hundred place

<h3>
Answer:</h3>
The radius would be <em>3.5 units</em>.
Step-by-step explanation:
This is because a radius is always half of a diameter.
By using that,
7 ÷ 2 = 3.5 units
Since there was no measurement listed in the question, the answer would be in "units."
