he has 16 laps left
Thank you for your question!
The formula is:
x + (x + 2) = -50
Solving:
2x + 2 = -50
2x = -52
x = -26
Finding the second number:
-26 + 2 = -24
-24,-26
Hope this helps!

Answer:
x = 55
Step-by-step explanation:
In a rhombus, each diagonal bisects a pair of opposite angles.
For this parallelogram t be a rhombus, the angles with measures 2x - 40 and x + 15 must be congruent.
2x - 40 = x + 15
Subtract x from both sides.
x - 40 = 15
Add 40 to both sides.
x = 55
