Answer questions below ASAP 5-1/2x=5/8x+2

1 answer:

5 0

Answer: x = 8/3 ; or, write as: 2 2/3; or, write as, 2.66666667 .
_________________________________________________________
Explanation:
_________________________________________________________

Given: 5 − 1/2 x = 5/8 x + 2 ;
______________________________________________________
Change the 1/2 x to "4/8 x" ;
_________________________________________________
Since "1/2" = "(1*4)/(2*4)" = "(4/8)"; and rewrite:
_________________________________________________
→ 5 − (4/8)x = (5/8)x + 2 ;
_________________________________________________
Subtract "5"; and add "(5/8)x" to EACH side of the equation:
________________________________________________
5 − (4/8)x − 5 + (5/8)x = (5/8)x + 2 − 5 + (5/8)x ;
_________________________________________________
to get:
_______________________________________
(1/8) x = (10/8)x − 3
___________________________________________________________
Multiply the entire equation (BOTH SIDES) by "8"; to get rid of the fraction:
_________________________________________________________

8 * { (1/8) x = (10/8)x − 3 };
______________________________
to get:
______________________________
x = 10x − 24 ;
___________________________________
Subtract "x" ; and add "24" ; to EACH side of the equation:
____________________________________________________
→ x − x + 24 = 10x − 24  − x + 24 ;
____________________________________________________
to get:
_____________________________________________________
→ 24 = 9x ; ↔ 9x = 24 ;
______________________________________
  → Divide EACH side of the equation by "9" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_______________________________________
  → 9x / 9 = 24 / 9 ;
_______________________________________
  → x = 24/9 = (24÷3)/ (9÷3) = 8/3
_______________________________________________
→ x = 8/3 ; or, write as: 2 2/3; or, write as, 2.66666667.

Diano4ka-milaya [45]

Answer:

dC = 2.44

Relative error = 19%

Step-by-step explanation:

$C = 35.74 + 0.6215*T - 35.75*v^(0.16) + 0.4275*T*v^(0.16)$

Δv = 3 ; ΔT = 1 , v = 23, T = 8

Use differential Calculus

$dC = Cv.dv + Ct.dt$

$Cv = dC/dv = -5.72*v^(-0.84) + 0.0684*T*v^(-0.84)\\Ct = dC/dT = 0.6215 + 0.4275*v^(0.16)\\dC = modulus (Cv.dv) + modulus (CT.dT)\\dC = (-5.72*v^(-0.84) + 0.0684*T*v^(-0.84))* 3 + (0.6215 + 0.4275*v^(0.16))*1\\dC = 2.44$

Relative Error

dC / C @(T = 8, v=23) * 100 = 19 %

Is x²-x divisible by 2?

bagirrra123 [75]

Answer:

Yes

Step-by-step explanation:

There are two cases: Case 1: x is even, so x can be modelled as a generic number 2n, where n is a positive integer. Clearly this product is divisible by two. ... Hence, it is safe to generalise that the term x²-x is divisible by 2 for any positive integer x.
