1+7/11 = 11/11+7/11 = 18/11
2+1/2 = 4/2+1/2 = 5/2
(18/11)/(5/2) = (18/11)*(2/5) = 36/55
I used mental math and it took a long time, but I got the answer of 2,499.
Answer:
A
Step-by-step explanation:
Slope is the first y - the second y divided by the first x- the second x. Therefore we take -8-4= -12 and -7-0= -7. Using the formula, we get -12/-7. The negatives cancel out and we get 12/7 which is A.
The answer is 150 because 30+150=180
Let us start dividing 30 by small prime numbers in increasing order .
the smallest prime number we use is 2
Let's divide 30 by 2 quotient is 15
so we get : 30 = 2* 15
15 is not a prime number , it can be factorized further .
now we start dividing 15
2 can not divide 15 so we move to next prime number that is 3
can 3 divide 15? yes .
we get a quotient 5
so 30 is now : 2* 15 = 2* 3*5
now we have to work on 5 but 5 is a prime number so we stop here .
the prime factorization of 30 is : 2* 3* 5
Answer : 2 *3*5
