1 min = 40 words
1 page = 500
It would take Regina 250 minutes to type 20 pages because we would first divide 500 words by 40 words (40 words equaling 1 minute) to first find out how long it took her to type 1 page. After finding it was 12.5 mins we then multiple, 12.5 x 20 which gives us 250 minutes. Which is also 4 hours and 10 minutes I believe.
The area would be 70cm because 10 x 7 = 70
I think 5006.2 because you move the decimal place 3 times
Start by multiplying 3 times 3x to get 9x. Then multiply 3 times -6 to get -18
After that your equation is 18=9x-18
Then your going to add 18 to each side so your equation should be 36=9x
Then devide each side by 9 so the answer will be x=4
Answer:
Step-by-step explanation:
To find the LCM of any integer, we take the product of all the <em>highest powers</em> of the factors that appear in the numbers. Factoring our three given expressions gives us the products
Our LCM will be a product of some powers of , , and . The most each factor occurs in the three expressions is once, so our least common multiple is
which can be simplified to
