Answer:
[tex] f = -15 [/tex]
Step-by-step explanation:
Given:
[tex] \frac{f}{3} + 22 = 17 [/tex]
Required:
Find the value of f
Solution:
[tex] \frac{f}{3} + 22 = 17 [/tex]
Subtract 22 on both sides
[tex] \frac{f}{3} + 22 - 22 = 17 - 22 [/tex]
[tex] \frac{f}{3} = -5 [/tex]
Multiply by 3 on both sides
[tex] 3(\frac{f}{3}) = 3(-5) [/tex]
[tex] f = -15 [/tex]

help please I'm like struggling
Answer: Choice 4) AC is four times longer than DF
=========================================================
Explanation:
Let's say AC is 4 units long. This makes AE half as long because AE is a radius of the larger circle and AC is the diameter of that same larger circle. So we know AE = 2. Segment DE is also a radius of that circle. So AE = DE = 2.
Segment DF is half as long as DE, leading to DF = DE/2 = 2/2 = 1.
We have DF = 1 and AC = 4. This shows AC is four times longer than DF.
--------------
Put another way:
AC = 2*(AE)
AC = 2*(DE)
AC = 2*(2*DF)
AC = (2*2)*DF
AC = 4*DF
So AC is four times longer than DF. We can replace DE with 2*DF since the diameter DE is twice as long compared the radius DF (for the smaller circle).
