12x + 6y = 120
-24x -6y =-180
-12x = -60
x = 5
4(5) + y = 30
20 + y = 30
y = 10
(5, 10)
Answer:
Based on the model,the length of the wall is <u>9/8</u> ft, the width of the walk is 1/2 ft, and the height of the wall is <u>11/8</u>. The volume of the portion of security wall that Tim has constructed so far is <u>99/128</u> cu ft.
Step-by-step explanation:
In the picture attached, part of a security world castle is shown.
length: 9 blocks, which is equivalent to 9*(1/8) = 9/8 ft
height: 11 blocks, which is equivalent to 11*(1/8) = 11/8 ft
width: 1/2 ft
Volume: length*height*width = (9/8)*(11/8)*(1/2) = (9 * 11 * 1)/(8 * 8 * 2) = 99/128 cu ft
Answer:
x < 3 or x > 9
Step-by-step explanation:
given 6| x - 6 | + 7 > 25 ( subtract 7 from both sides )
6| x - 6 | > 18 ( divide both sides by 6 )
| x - 6 | > 3
Inequalities of the form | x | > a always have solutions of the form
x < - a OR x > a, hence
x - 6 < - 3 or x - 6 > 3 ( add 6 to both sides in both inequalities )
x < 3 or x > 9
