The square root of 121 is 11
Step-by-step explanation:
y+6y-2= -12
7y-2 = -12-2
7y. = -14
7y/7y = -14/7y
y = -2
-5x+-3x
-8x-2-2= -12
-8x -4= -12-4
-8x = -16
-8x/-8x = -16/-8x
x = -2
Known:
1 link = 8 inches
1 inch = 0.083 feet
108 inches = 9 feet
To find how many links:
108/8= 13.5 links
(82 + 78 + 82 + 77 + x) / 5 = 80
319 + x = 80 * 5
319 + x = 400
x = 400 - 319
x = 81 <== she can get an 81 on it and still get a B
