F(x) = 2 x - 5
15 = 2 x - 5
2 x - 5 = 15
2 x = 15 + 5
2 x = 20
x = 20 / 2
x = 10
hope this helps!
Answer:
The larger angle is 144 degrees and the smaller angle is 36 degrees
Step-by-step explanation:
Because this is a supplementary angle you have to find out what x is to solve this equation 
Because 2.4x and 9.6x are like terms we add them 
So now to find x we divide 180 by 12 to get 15 
We replace the x with 15 
We add 36 and 144 which equals 180
Answer:
B
Step-by-step explanation:
log4x = 2.1
logx/log4 = 2.1
logx = log(4) x 2.1
logx = 1.264
x = 10^(1.264)
x = 18.38 (to two d.p)
Round 31.9 up to 32 so you can divide it by 4 to get about 8.
Hello from MrBillDoesMath!
Answer: Yes, (8 1/2) /`17 = ( 17 11/12) /23
** I think you meant 11 1/2 is to 23 NOT 17 11 1/2 is to 23"
Discussion:
First, 8 1/2 = 17/2 and
(17/2
) / 17 = 1/2
Second 11 1/2 = 23/2 and
(23/2)/ 23 = 1/2
IN other words, the ratiors are the same:
8 1/2 11 1/2
------- = -------
17 23
Thank you,
MrB
