Answer:
205.92
Step-by-step explanation:
just basic math
Since sides kl and kj are congruent that means that angles klj and kjl are congruent. if angle klj is 58 then that means kjl is also 58. so you take the total number of degrees in a triangle (180) and subtract 58 and 58 (116) which leaves you with 64 ( the degree measure of lkj)
4x - y = 10, y = 2x - 2
4x - (2x -2) = 10
4x - 2x + 2 = 10
2x = 8
x = 4
4(4) - y = 10
-y = -6
y = 6
So x = 4 y= 6
Hope this helps!

4x - 3y = 3...multiply by 4
5x - 4y = 3...multiply by -3
--------------
16x - 12y = 12 (result of multiplying by 4)
-15x + 12y = - 9 (result of multiplying by -3)
---------------add
x = 3
4x - 3y = 3
4(3) - 3y = 3
12 - 3y = 3
-3y = 3 - 12
-3y = - 9
y = -9/-3
y = 3
solution is (3,3).....and the x = 3
Answer:
Jeremiah travels at 26.667 mi/hr and Ermias travels at 18.667 mi/hr.
Step-by-step explanation:
Say Ermias' speed is 's' and Jeremiah's is 'v'
distance = rate * time
distance = ( v * time) + ( s * time)
v = s + 8
240mi = ( (s+8) * 8 ) + ( s + 8)
240 = (8s +64) + s + 8
240 = 9s + 72
240 - 72 = 9 s
168 = 9 s
18.6666667 = s
v = 18.6666667 + 8
v = 26.6666667
