Answer:
Length of segment BD = 42 units
Step-by-step explanation:
Since C is the midpoint of AB,
Then segment AC = segment CD
Since B is the midpoint of BC,
Then the length of segment AB = Length of segment BC = 14 units
Length of AC = 2 × (14)
= 28 units
Length of AC = length of CD = 28 units
Length of segment BD = Length of BC + length of CD
= 14 + 28
= 42 units
Therefore, length of segment BD is 42 units.
Answer:
Step-by-step explanation:
X/25=16/x
Cross multiply to get
X^2=square root 400
Un square to get 20
It’s 20 meters
Answer:
the expression is x= 2.5 * z/√y
Step-by-step explanation:
since x is proportional to z and since x varies inversely as the square root of y
x= a * z/√y
then
a = x*√y /z
replacing values
a = x*√y /z = 6*√25 /12 = 30/12 = 10/4=2.5
therefore
x= 2.5 * z/√y
Answer:
a=6
Step-by-step explanation:
distribute:
3a-15-6=-15
combine like terms:
3a-21=-15
add 21 to each side:
3a=6
divide by 3:
a=2
Answer:
11 and 16
Step-by-step explanation:
A good way to solve these is to work backwards.
X= larger and Y= smaller
if X is 5 more than 2Y than subtract 5 from the total
38 - 5 = 33
divide by 3
33/3 = 11
11 = Y and double that is 22 so add the five back into X and you get 16
