Answer:
x > -2.5
Step-by-step explanation:
1) 5.1 (3 + 2.2x) > -14.25 - 6 (1.7x + 4)
2) 15.3 + 11.22x > -14.25 - 10.2x - 24
3) 15.3 + 11.22x > -38.25 - 10.2x
4) 11.22x + 10.2x > -38.25 - 15.3
5) 21.42x > -53.55
6) x > -2.5
Alternate forms
x > -5/2x or x > -2 1/2
Answer:
3x + 6y
Step-by-step explanation:
so the perimeter is 12x + 8y and a side is 4x-2y so that means that side and the side across is 8x-4y so you put it all to one side to get 6x +12y then divide that by 2 to find 1 side so the side is 3x + 6y
Answer:
SA= 28 in^2
V= 14 in^3
Step-by-step explanation:
circumference= 2πr
9.4 = 2πr
r = 1.496
surface area of a ball = 
= 
=28 in^2
volume of a ball= 
= 
=14 in^3
