1) u + 2 = 4
u = 2
2) -5 = s - 3
-2 = s
3) 5/13t = -9
t = -9 × 13/5
t = -39/5
t = -7 4/5
4) 6 = x + 2/3
x = 6 - 2/3
x = 5 1/3
5) 13 + w/7 = -18
w/7 = -18 - 13
w/7 = -31
w = -31 × 7
w = -217
6) 17 = -13 - 8x
-8x = 17 + 13
-8x = 30
x = 30/-8
x = -15/4
x = - 3 3/4

Answer:
ab<6 units
Step-by-step explanation:
One of the basic property of any triangle is that the sum of the length of any two sides of a triangle is always greater than the length of the third side.
Here we are given a triangle abc, in whicn bc=4
ac= 8-ab
If have to make some conclusion about ab.
As per the property discussed above
ab<ac+bc
ab<8-ab+4
2ab<12
ab<6
Hence the length of ab must be less than 6 units
$49.50 the jacket costs this because her total amount was $66. to find total money I said 3/4x - 1/4x = $33 so 1/2x =$33 and x= $66. then multiply the total by 3/4 to get $49.50
