Answer:
36
Step-by-step explanation:
GCF or greatest common factor is the greater/biggest number that can factor for both numbers. To find GCF, you need to make factor of both number
72- 2 * 2 * 2 * 3 * 3 = 2^3 * 3^2
36= 2 * 2 * 3 * 3 = 2^2 * 3^2
After this, you can compare the factor of both numbers. Both numbers can be divided by 2, but 36 can be divided 2 times while 72 can be divided 3 times. In this case, you take the lowest number which is 2. Both numbers can be divided by 3^2 so you can take it whole.
The factor will be: 2^2 * 3 *2= 4 * 9= 36
There are multiple ways to do this.
The easiest is to just continuously subtract 7 from 65 the numbers of times needed.
But most math teachers will have you use the equation ar^n-1 where a= the first term (65), r=ratio (-7), and n=the term you need (second, fifth, and ninth).
So to solve you just plug your values in as so
AR^n-1
(65)(-7)^2-1(65)(-7)^5-1
(65)(-7)^9-1
Something percent of a number must be smaller than the number.
And also, 39% of a number is equal to 39/100 multiplied by the number.
Thus:
39/100 * 1200
39/1 * 12
468
Answer:
x = 7.8
Step-by-step explanation:
2.6 + x = 10.4
-2.6 -2.6
x = 7.8
You do the inverse operations to find out x
