Answer:
23
Step-by-step explanation:
7/8 = 0.875
it is a terminating decimal, because it ends, unlike a repeating decimal, which goes on forever.
Answer:
x = 11
BD = 10
Step-by-step explanation:
Solving for x
The opposite sides if a parallelogram are equal and parallel.
Hence,
2x - 5 = 17
Collecting like terms:
2x = 17 + 5
2x = 22
x = 11
If E is a midpoint, then BE equals to DE
Since BE = 5, then
BD = 2 * BE
BD = 10
