3( x - 1 ) = 2 x + 5
Expand 3(x-1) :
3*x - 3 x 1
3 x - 3 = 2 x + 5
Add 3 both sides :
3 x - 3 + 3 = 2 x + 5 + 3
3 x = 2 x + 8
3x - 2 x = 8
x = 8
hope this helps!
Answer:
5 shares if only whole shares are allowed
5.53 shares if fractional shares are allowed
Step-by-step explanation:
112(0.80) / 16.20 = 5.530864
2a + b = 9.4
There are 3 parts, 2 go to Rod A, 1 go to Rod B.
9.4 / 3 = 3.13333 recurring
Rod A = 2(3.13)
= 6.26
Rod B =
3.13
Rounding, Rod A = 6.3 , Rod B = 3.1
