D-10-2d+7=8+d-10-3d

TEA [102]

$Solution,solve\:for\:d,\:d-10-2d+7=8+d-10-3d\quad :\quad d=1$

$Steps:$

$d-10-2d+7=8+d-10-3d$

$\mathrm{Subtract\:}d-10\mathrm{\:from\:both\:sides},\\d-10-2d+7-\left(d-10\right)=8+d-10-3d-\left(d-10\right)$

$\mathrm{Refine},\\-2d+7=8-3d$

$\mathrm{Subtract\:}7\mathrm{\:from\:both\:sides},\\-2d+7-7=8-3d-7$

$\mathrm{Simplify},\\-2d=-3d+1$

$\mathrm{Add\:}3d\mathrm{\:to\:both\:sides},\\-2d+3d=-3d+1+3d$

$\mathrm{Simplify},\\d=1$

$\mathrm{The\:Correct\:Answer\:is\:d=1}$

$\mathrm{Hope\:This\:Helps!!!}$

jonny [76]

Answer:

The growth rate for the period was of 17.86%.

Step-by-step explanation:

To find the growth rate as a percent, we multiply the change by 100, and divide by the initial value.

A house cost $112,000 in 2010. By the year 2015, the house had a value of $132,000.

Change: 132 - 112 = 20

Initial value: 112

Growth rate as a percent:

20*100/112 = 17.86%

The growth rate for the period was of 17.86%.
