Answer:
C. m ≥ 9
Step-by-step explanation:
7m -2 ≥ 61
7m ≥ 61+2
7m ≥ 63
m ≥ 63/7
m ≥ 9
A is the correct answer. When put into calculator, the decimals ends.
We have FIVE cats that each ate 1/4 cup of canned food.
Then, the five of them together ate:
5 times 1/4 cup This in mathematical expression is a profduct of an integer value (5) times the fraction (1/4) which we know how to multiply based on the problems we solved a few minutes ago:
5 * 1/4 = 5/1 * 1/4 = (5 * 1) / (1 * 4) = 5/4 cups
This answer can also be written as a MIXED number given that 5/4 is an IMPROPER fraction (a fraction with numerator larger than the denominator)
5/4 = 1 1/4
Not sure what answer your teacher would prefer. It depends on whether he/she wants you to use fractions or mixed numbers.
The answer would be 84 because 2miles is equal to 24 minutes so you would break that in half down to one mile. One mile would be 12 minutes. So you would multiply 12 times 7 which equals 84 which would be your answer.
You cannot memorize a whole multiplication chart in one day, but if you go online and search multiplication stories, there may be some stories to help you memorize your facts quicker depending on your learning style. Also try and remember that any number times any number is just that number being added over and over again a certain amount of times. For example: 3*4= 3+3+3+3 Hope this helps :)
