0.5x+7/3 = 21/4 cross multiply

TiliK225 [7]

Solving the expression $\frac{0.5x+7}{3}=\frac{21}{4}$ we get: $x=\frac{35}{2}\,\,or\,\,x=17.5$

Step-by-step explanation:

Solving the expression: $\frac{0.5x+7}{3}=\frac{21}{4}$

Solving by cross multiplying:

$\frac{0.5x+7}{3}=\frac{21}{4}\\(0.5x+7)*4=21*3\\Simplifying:\\2x+28=63\\Adding\,\,-28\,\,on\,\,both\,\,sides:\\2x+28-28=63-28\\2x=35\\Divide\,\,both\,\,sides\,\,by\,\,2\\\frac{2x}{2}=\frac{35}{2}\\x=\frac{35}{2}\,\,or\,\,x=17.5$

So, solving the expression $\frac{0.5x+7}{3}=\frac{21}{4}$ we get: $x=\frac{35}{2}\,\,or\,\,x=17.5$

If $7000 is placed in account with an annual interest of 5.5% how long will it take the amount to double if the interest is comp

julsineya [31]

$A=P(1+ \frac{r}{n})^ \frac{t}{n}$
A=future amount
P=present amount
r=rate in decimal
n=number of times per year compounded
t=time in years

how many years to double
basically
A=2P at t=?
so we can simplify and ignore the pricipal given and do
$2=(1+ \frac{r}{n})^ \frac{t}{n}$
r=5.5%=0.055
n=1
t=t

$2=(1+ \frac{0.055}{1})^ \frac{t}{1}$
$2=(1+ 0.055)^t$
$2=(1.055)^t$
take the ln of both sides
$ln2=t(ln(1.055))$
divide both sides by ln1.055
$\frac{ln2}{ln1.055}=t$
use calculator to aproximate
12.9462=t
