5x + 25y = 60....multiply by -3
3x + 15y = 42....multiply by 5
-------------------
-15x - 75y = - 180 (result of multiplying by -3)
15x + 75y = 210 (result of multiplying by 5)
-------------------add
0 = 30...incorrect.....this system has no solutions
SOLUTION:
= 3 / 4
= 75 / 100
= 0.75
Therefore, Robert came in first for 0.75 of his race.
Hope this helps. :)
Have a lovely day! <3
To find 75% of 200, we can multiply two fractions.
75/100 * 200/1
Now, just multiply the numerators and the denominators separately.
75 * 200 = 15000
100 * 1 = 100
Now, divide.
15000/100 = 150
<h3>75% of 200 is 150.</h3>

Answer:
(4,2)
Step-by-step explanation:
Just by looking at the graph, you can see that they intersect at (4,2). But just to check:
x - 2 = -0.5x + 4
1.5x = 6
x = 4
y = 4 - 2 = 2
(4,2)
