Answer:
1/2, 7/11, 3/4
Step-by-step explanation:
Answer:
47. 1 5/8
48. 1 1/12
Step-by-step explanation:
<em>47. </em>
<em>First, convert the denominators to be the same.</em>
8 1/2 minutes, Ruby's mile time, can be converted to 8 4/8.
<em>Then subtract.</em>
8 4/8 - 6 7/8 = 1 5/8
<em>48.</em>
<em>Make sure the denominators are the same. Both denominators can be multiplied by 3 or 4 to become 12.</em>
1 1/4 can be multiplied by 3 to get 1 3/12. And 1 1/3 can be multiplied by 4 to get 2 4/12.
<em>Then subtract.</em>
2 4/12 - 1 1/3 = 1 1/12
Answer:
D
Step-by-step explanation:
Because his boots are muddy, you can infer the place he goes rains alot, so, his environment for the job is most likely outside, such as the mountains or forests, so the answer is D.
Hope this helped! :D
There are 3 ways of solving a simultaneous problem, substitution method, elimination method and Gauss-Jordan method. I'm gonna use the substitution method since it's easier and i think it would suit your level more.
First let's try solving for y since it's easier to start with.
Firstly we have to find an equation for x:

Great, now we can use the substitution method to find the value of y using the first equation:

Now we know that y=1 we can solve the first equation we made:

And the answer is 
Double check:

And that's our final answer! (4,1)
Answer:
put x=-1, and the rest will be easy
