suppose you currently own a clothes dryer that costs $20/month to operate. A new efficient dryer cost $510 and has an estimated
prohojiy [21]

The first dryer is 25 a month, so 25 times x, or 25x.  

The second is 15 per month, plus an additional $710 cost, so 15x + 710. Set these equations equal to each other to find x, the amount of months where the cost of the first dryer will equal the cost of the second dryer.  

25x= 710 + 15x  

-15x -15x  

10x=710  

x=71 months

Hope this helps

The length of a rectangle is twice it’s width. If the area of the rectangle is 162m ^2,find its perimeter
GalinKa [24]

Answer:

{ \tt{area = length \times width}} \\ { \tt{162 = 2w \times w}} \\ { \tt{162 = 2 {w}^{2} }} \\ { \tt{ {w}^{2}  = 81}} \\ { \tt{w = 9}}

  • width, w = 9 m
  • length, l = 2 × 9 = 18 m

{ \tt{perimeter = 2(l + w)}} \\ { \tt{p = 2(18 + 9)}} \\ { \tt{p = 2 \times 27}} \\  \\ { \underline{ \tt{ \:  \: perimeter = 54 \: m \:  \: }}}
