What is the value of x in the equation 2.5 (6x - 4) = 10 + 4 (1.5 + 0.5x)

ioda

Answer:

x = 2

Step-by-step explanation:

Given

2.5(6x-4) = 10 + 4 (1.5+0.5x)

First of all we will have to solve the parenthesis

(2.5)(6x)-(2.5)(4) = 10 + (4)(1.5)+(4)(0.5x)

15x-10 = 10+6+2x

We have to isolate x so that we can find its value

15x-10 = 16+2x

15x = 16+2x+10

15x-2x = 26

13x = 26

13x/13 = 26/13

x = 2 ..

Hello, could anyone please help me with my homework?

IRINA_888 [86]

Answer: See below

Step-by-step explanation:

$100\left(\frac{1}{2}\right)^{\frac{t}{214}}=20$

$\mathrm{Divide\:both\:sides\:by\:}100$

$\frac{100\left(\frac{1}{2}\right)^{\frac{t}{214}}}{100}=\frac{20}{100}$

$Simplify$

$\left(\frac{1}{2}\right)^{\frac{t}{214}}=\frac{1}{5}$

$\mathrm{If\:}f\left(x\right)=g\left(x\right)\mathrm{,\:then\:}\ln \left(f\left(x\right)\right)=\ln \left(g\left(x\right)\right)$

$\ln \left(\left(\frac{1}{2}\right)^{\frac{t}{214}}\right)=\ln \left(\frac{1}{5}\right)$

$\mathrm{Apply\:log\:rule\:}\log _a\left(x^b\right)=b\cdot \log _a\left(x\right)$

$\ln \left(\left(\frac{1}{2}\right)^{\frac{t}{214}}\right)=\frac{t}{214}\ln \left(\frac{1}{2}\right)$

$\frac{t}{214}\ln \left(\frac{1}{2}\right)=\ln \left(\frac{1}{5}\right)$

$\frac{\ln \left(\frac{1}{2}\right)t}{214}=\ln \left(\frac{1}{5}\right)$

$\mathrm{Multiply\:both\:sides\:by\:}214$

$\frac{214\ln \left(\frac{1}{2}\right)t}{214}=214\ln \left(\frac{1}{5}\right)$

$-\ln \left(2\right)t=-214\ln \left(5\right)$

$\mathrm{Divide\:both\:sides\:by\:}-\ln \left(2\right)$

$\frac{-\ln \left(2\right)t}{-\ln \left(2\right)}=\frac{-214\ln \left(5\right)}{-\ln \left(2\right)}$

$t=\frac{214\ln \left(5\right)}{\ln \left(2\right)}$ or $\mathrm{Decimal}:\quad t=496.89261\dots$
