Answer:
3
Step-by-step explanation:
Answer: The fraction x = 1/2 or its equivalent decimal form x = 0.5
================================================
Work Shown:
AE = 2*(BD)
4x+8 = 2*(4x+3)
4x+8 = 8x+6
8-6 = 8x-4x
2 = 4x
4x = 2
x = 2/4
x = 1/2
x = 0.5
note: the first equation is set up basically saying that AE is twice that of BD; put another way, BD is half as long as AE. This is one property of midsegments. Another property is that AE and BD are parallel.
another note: if x = 0.5, then AE = 4*x+8 = 4*0.5+8 = 10 while BD = 4*x+3 = 4*0.5+3 = 5, showing that AE is indeed two times longer than BD.
Answer:
C. 8
Step-by-step explanation:
Answer:
2.3+r=7.1
move all terms to the left:
2.3+r-(7.1)=0
add all the numbers together, and all the variables
r-4.8=0
move all terms containing r to the left, all other terms to the right
r=4.8 is the answer
