Solve for x: two thirds(x − 2) = 4x.

Sveta_85 [38]

Answer:

$x = - 0.4$

Step-by-step explanation:

$\frac{2}{3} (x - 2) = 4x$

Expand with the distributive rule:

$\frac{2}{3} x - \frac{2}{3} \times 2 = 4x$

$\frac{2}{3} x - \frac{4}{3} = 4x$

Add 4/3 to both sides:

$\frac{2}{3} x = 4x + \frac{4}{3}$

Subtract 4x from both sides

$- \frac{10}{3} x = \frac{4}{3}$

$- 10x = 4$

$x = - 0.4$

Please help me with this #7

$\text{Given that,}\\\\\text{First term,}~ a_1 = -8~~~~...(i)\\\\\text{12th term,}~ a_{12} = -52~~~...(ii)\\\\\text{Common difference is d.}\\\\(ii)\div(i):\\\\\dfrac{a_{12}}{a_1} = \dfrac{-52}{-8}\\\\\\\implies \dfrac{a_1 + (12-1)d}{a_1} = \dfrac{52}8\\\\\\\implies \dfrac{-8+11d}{-8} = \dfrac{52}8\\ \\\\\implies -8+11d = \dfrac{52(-8)}8\\\\\\\implies -8+11d = -52\\\\\\\implies 11d = -44\\\\\\ \implies d = \dfrac{-44}{11} = -4$

$\\\text{86th term,} ~a_{86} = a+ (86-1)d \\\\~~~~~~~~~~~~~~~~~~~~=-8+85d\\\\~~~~~~~~~~~~~~~~~~~~=-8+85(-4)\\\\~~~~~~~~~~~~~~~~~~~~=-348\\\\\text{Hence, the 86th term is}~ -348$
