55 minus 18 is 37 and then it would be 37,000 and then you just convert it so it is 37% of 100 (the answer is 37%)
Answer:
(p,r) = (1/3, 2/9)
Step-by-step explanation:
Here, we want to solve a system of equations
We can rewrite the second equation by dividing through by 2
So we have;
4p + 3r = 2
and
5p - 3r = 1
Add both equations:
9p = 3
p = 3/9
p = 1/3
Recall ;
5p - 3r = 1
3r = 5p - 1
Substitute the value or p here
3r = 5(1/3)-1
3r = 5/3 - 1
3r = 2/3
r = 2/9
So we have the solution set as;
(p,r) = (1/3 , 2/9)
I believe your answer would be C. Hope this helped!
Convert 2/5, 1/4 and 7/10 to fractions with like denominators.
Since 8/20,5/20 and 14/20 have the same denominator, add their numerators to add them up.
If it travels at a constant speed for twice the amount of time, the train should travel twice the distance, or 24 * 2 = 48 km.
