Step-by-step explanation:
45+90+x=180
135+x=180
x=180-135
x=45
The average is found by adding the numbers and dividing by 2.
Since the average is 17, the total of the two numbers must equal 17 x 2 = 34.
One number is given as 11, so subtract 11 from 34:
34 - 11 = 23
The other number is 23.
Too check: add 11 and 23 and then divide by 2:
11 + 23 = 34
34/2 = 17.
Answer:
n = 70
Step-by-step explanation:
14 * x < 80
x = 6 won't work
14 * 6 = 84 which beyond the boundry.
14 * 5 = 70 which is less than 80 and is divisible by 14
14 * 3 = 42
70 does not have a 3 in it.
So the largest number that has 14 in it and is less than 80 is 70
Answer:
i'll explain it to you
Step-by-step explanation: look for a number line that has 180, 120, and 15 you see you have to multiply 15 by 12 dozen cupcakes which equals to 180 that way she earns more than $120
Answer:
"greatest common factor" (GCF) or "greatest common divisor" (GCD)
Step-by-step explanation:
Apparently, you're looking for the term that has the given definition. It is called the GCF or GCD, the "greatest common factor" or the "greatest common divisor."
_____
The GCF or GCD can be found a couple of ways. One way is to find the prime factors of the numbers involved, then identify the lowest power of each of the unique prime factors that are common to all numbers. The product of those numbers is the GCF.
<u>Example</u>:
GCF(6, 9)
can be found from the prime factors:
The unique factors are 2 and 3. Only the factor 3 is common to both numbers, and its lowest power is 1. Thus ...
GCF(6, 9) = 3¹ = 3
__
Another way to find the GCD is to use Euclid's Algorithm. At each step of the algorithm, the largest number modulo the smallest number is found. If that is not zero, the largest number is replaced by the result, and the process repeated. If the result is zero, the smallest number is the GCD.
GCD(6, 9) = 9 mod 6 = 3 . . . . . (6 mod 3 = 0, so 3 is the GCD)
