Answer:
5X-6)+(5X-6)+X+X=252 , now lets add all the X together, and then add the whole numbers.
12X-12=252 , now lets work this by adding 12 on each side of the equation:
12X-12+12=252+12
12X=264 , divide both sides by 12.
X=22
Now lets prove X =22:
(5·22–6)+(5·22–6)+22+22=252
(110–6)+(110–6)+22+22=252
104+104+44=252
208+44=252
252=252Therefore the length is 104 feet each and the width is 22 feet each.
Answer:
Melba works more
Step-by-step explanation:
We need to compare with the same units
Lets convert hours to minutes
1 hour = 60 minutes
8 hours* 60 minutes/1hour = 480 minutes
Keith works 480 minutes
Melba works 2250 minutes

Don't cry!! You got this! Just take it one step at a time and list your known values:
h = 5 m
r = 5 m
The volume of a cone is V = (1/3)πr^2h
V = (1/3)(3.14)(5)^2(5) = 130.83 m^3
I believe in you! I hope this helps!
Answer:
1. x = 3 or x = -8
2. x = -2 or x = 10
Step-by-step explanation:
<u>1. |2x + 5| = 11</u>
2x + 5 = 11 Or 2x + 5 = -11
-5 -5 -5 -5
----------------- -----------------
2x = 6 2x = -16
/2 /2 /2 /2
----------------- -----------------
x = 3 x = -8
<u>2. 3|x - 4| + 1 = 19</u>
3|x - 4| + 1 = 19
-1 -1
----------------------
3|x - 4| = 18
/3 /3
----------------------
|x - 4| = 6
x - 4 = -6 Or x - 4 = 6
+4 +4 +4 +4
----------------- -----------------
x = -2 x = 10
