The greatest common factor (GCF) of 28 and 32 is: 4
<span>To find the GCF we have to list the factors of each number we are given. In this case, 28 and 32 is our numbers we have to list factors from. Our minimum factor is the original number we started with.
Factors of 28: 1, 2, 4, 7, 14, 28
Factors of 32: 1, 2, 4, 8, 16, 32
</span><span>Find the common factor out of them, and then find the factor with the highest value. The common factors of each numbers are 1, 2, and 4. The highest number out of that is 4, so 4 is our GCF.</span>
56.52 inches because 18 is the diameter and 18 times 3.14 is 56.52
First of all, observe that all fractions exist as long as b is not zero.
Multiply both numerator and denominator of the first fraction by 3:

Now all fractions have the same denominator. Under the assumption that b is not zero, multiply both sides by 3b:

Subtract 3b from both sides:

Subtract 2 from both sides:

Divide both sides by 2:

Answer:
It is arithmetic progression
Step-by-step explanation:
If wwe see, the numbers are going down by 3 each time, therfore the common difference is 3
The <em>correct answer</em> is:
C) x/21
Explanation:
Since Person 1 can complete the entire job (100% = 1/1 = 1) in 21 minutes, this person can complete 1/21 of the job per minute. This is Person 1's rate. If x is the amount of time it takes both people together to finish the job, then the amount of work Person 1 does would be (1/21)(x) = x/21.
