Write 7 as a fraction with the 9 in the denominator

2 answers:

6 0

So 7=7/1
to put a 9 in the bottom and make the fraction stay the same, multiply it by 1
or 9/9 since 9/9=1 so
7/1 times 9/9=(7 times 9)/(1 times 9)=63/9
answe ris 63/9

63/9 would be the answer because 63 divided by 9 would be equivalent to 7/1 or 7.

hillary is cycling across montana taking a 845 mile course . the first week she covered.320 miles. the second week she traveled

Blababa [14]

Answer:

175 miles

Step-by-step explanation:

Hillary has travelled

320 + 350 = 670 miles

in the first two weeks.

Therefore, Hillary starts with 670 miles and needs to add a certain number of miles "x" to get 845 in total.

670 + x = 845

And if we subtract 670 from both sides:

x = 845 - 670 = 175

175 miles

23 + 8m + 4n - 5m - 27

mylen [45]

Answer:

$-4 + 3m + 4n$

Step-by-step explanation:

In this question, you are combining like terms, meaning doing equations to numbers that fit with only each other.

So we should start on the number without variables:

23 and 27

Match them up together and you should find your first equation:

23 - 7

==> -4

So we should have -4 + 8m + 4n - 5m

Now we should combine the numbers with the variable of m:

8m and 5m

Match them up together and you should find your first equation:

8m - 5m

==> 3m

So we should now have -4 + 3m + 4n

Since there are no other variables of n, we are all done:

-4 + 3m + 4n is your final answer
