Answer:
it will be (3)
Step-by-step explanation:
since DB is a median
then DB= half AC , AB=BC
then AB=BD
then the two triangles are isosceles
Answer:
Step-by-step explanation:
Given:
1. 1/5x - 1/3y = -1
2. -3/4x +1/3y = 12
Multiplying equation 1 by 15 and equation 2 by 12
3. 3x - 5y = -15
4. -9x + 4y = 144
and then Solving both equations simultaneously, since x = -20 as stated in the question and by confirmation,
Using equation 3 or 4 to solve for y,
3(-20) - 5y = -15
-5y = 60 - 15
y = 45/-5
= -9
y = -9
It's D 4 3/8 miles
First you have to multiply 2 1/2 for the mile and 1 3/4 for the inches. You will get 4.375.Convert it to fraction which is 35/8 and simplify it to get 4 3/8.
Hope this helps!
