28/x = 40/100
Cross multiply
40x = 28(100)
40x = 2800
Divide both sides by 40
x = 70 students
we have
6x+3y=12 -----> line p
Find the slope
3y=-6x+12
y=-2x+4
m=-2
-4x=2y-2 -----> line Q
2y=-4x+2
y=-2x+1
m=-2
therefore
the lines are parallel because their slopes are equal
Simply add the three decimals to find Kareem's total distance.
1.6 + 11.5 + 15 = 28.1
(0.6 + 0.5 = 1.1, 1 + 11 + 15 = 27, 27 + 1.1 = 28.1)
<h2>Answer:</h2>
<u>Kareem ran </u><u>28.1 km</u><u> on those three days.</u>
I hope this helps :)
1. The point where x and y axis meet is the intersect, origin of the coordinate system (0,0)
2. m<A and m<D = 90 then <A and D are complementary angles
3. 180 angle or linear rays
4. Obtuse angle measure more than 90
5. Segment of equal lengths are congruent segments
6. Lines that meet at a 90 angle are perpendicular
