Lydia spent 4/5 of her money on a mobile phone and 2/3 of the remaining amount on a bag. She had $60 left. How much more money did she spend on the mobile phone than on the bag?

she spend $600 more on phone than on bag.

part A:

let the money she have be m,

she spent on mobile phone: →

remaining: →

she spent on bag: →

remaining: →

so,

 = 60

m = $900

part B:

money she spent on mobile phone:    →    →  $720

money she spent on bag:  →   → $120

more money she spent on mobile phone than on bag:

mobile phone cost - bag cost

720 - 120

$600

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
