Answer:
c
Step-by-step explanation:
y = 
x + 2 → (1)
2y = 5x + 4 ( divide through by 2 )
y = x + 2 → (2)
the 2 equations are the same and will have infinitely many solutions
$87.5 because 30% of 125 is 37.5 so 125-37.5 is 87.5
Answer:
x = 58 degrees
Step-by-step explanation:
Angle K (which is x) and Angle I are congruent corresponding angles with one another, so if, as an example, Angle I was 10, Angle K would also be 10.
<u><em>All you need to do in this case is add Angle H (56) and Angle A (66) together:</em></u>
56 + 66 = 122
<u><em>Then subtract 122 from 180 (because triangles add up to 180 degrees) to get x:</em></u>
180 - 122 = 58
So, x = 58 degrees.
Answer:
Your answer is A.
Hope this helps!
Step-by-step explanation:
Line r's equation is
y = - 4/3x - 4
And Line s's equation is
y = 2/5x - 2
The 40 ml solution is said to be created from 10 ml and 30
ml solutions. In mixture problems, we equate the final mixture to its
compositions given the concentration for each. A 10 ml has 20% acid and the 30 ml has C
(unknown). We can write the total liters for 10 ml as 10(.2) and 30(c) for the
30 ml. when two solutions were added, it should be equal to 40ml with 32% acid.
Therefore, it should be written as 10(.2) + 30(c) = 40(.32). The answer is A
