i got it right
The rhombus has four equal sides ⇒ JK=ML=KL
4x-8 = x+13
4x - x = 13 + 8
3x = 21
x = 7
ML = x+13 = 7 + 13 = 20
KL=ML ⇒
6y+2 = 20
6y = 20-2
6y = 18
y = 18/6
y = 3
Answer:
Gabriella's average original speed was 56
Step-by-step explanation:
Let's use the equation that defines the average speed "v" of Gabriella during the time (t) that her trip took:
Next let's write a similar average speed equation for the case in which she drove at (v - 7 mi/h) during the same time "t" and covered 350 miles:
Notice that the time "t" in the denominator appears equally in both equations we wrote, so let's isolate them on the right:
now equal both expression since they both share the same value on the right, and solve for the unknown "v":
