My best guess would be A but I am not 100% sure
2(4z - 3 -1) = 166 - 46
2*(4z - 4) = 120
(4z - 4) = 120/2
4z - 4 = 60
4z = 60 + 4
4z = 64
z = 64/4
z = 16
This would be the same as 8x=-72, when you divide everything by 8, you get
x = -9
C^2 + 11c = 12
c^2 + 2[11/2] c = 12
[c + 11/2] ^2 - [11/2]^2 = 12
[c +11/2]^2 = 12 +[11/2]^2
[c +11/2]^2 = 12 + 121/4
[c +11/2]^2 =[48+121]/4
[c +11/2]^2 = 169/4 ----> This is the resulting equation
Solving it you get:
c + 11/2 = +/- √(169/4)
c + 11/2 = +/- 13/2
c = 13/2 - 11/2 =2/2 = 1 and
c = -13/2 - 11/2 = - 24/2 = -12
Answer: 665,640 minutes
Step-by-step explanation:
Dimensional analysis: dividing out common units like dividing out common factors
<em>For ex: </em>3/5* 5/7= 3/7
cross out the fives and turn them into 1
For dimensional analysis you just cross out the units.
days-->hours-->minutes
462.25d/1* 24h/1d* 60m/1h= 665,640 minutes
Cross out the d's and h's.
You are left with minutes on the top and no units on bottom.
Just multiply across to get the answer 665,640 minutes
