Find the difference. Simplify. Combine Like Terms.

Answer:

$\huge{ \fbox{ \sf{ - 2y - 30}}}$

Step-by-step explanation:

$\star{ \sf{ \: (4y - 10) - (6y + 20)}}$

$\text{Step \: 1 }\: : \sf{While \: subtracting \: sign \: of \: each \: term \: of \: the \: second \: expression \: changes}$

$\hookrightarrow{ \sf{4y - 10 - 6y - 20}}$

$\text{Step \: 2 \: : \sf Collect \: like \: terms}$

$\sf{Like \: terms \: are \: those \: which \: have \: the \: same \: base.}$

$\hookrightarrow{ \sf{4y - 6y - 10 - 20}}$

$\hookrightarrow{ \sf{ - 2y - 10 - 20}}$

$\text{Step \: 3 \: : \sf{Calculate}}$

$\underline{ \text{Remember!}} : \sf{The \: negative \: integers \: are \:always \: added \: but \: posses \: the \: negative \: ( - ) \: sign.}$

$\hookrightarrow{ \sf{ - 2y - 30}}$

Hope I helped!

By selling a stool for rupees 67.50,a carpenter loses 10%.how much percent would he gain or lose by selling it for rupees 82.50.

valentina_108 [34]

Let the actual value of the stool be x.

So if the carpenter sells the stool x rupees he neither loses, now wins anything.

67.50 is the value x - 10% of x, that is:

67.50=x-0.1x
67.50=0.9x

x=67.50/0.9=75 (rupees) is the actual value of the stool.

Selling the stool for 82.50 rupees, the carpenter clearly would make a profit, say of y% of that actual value, that is y%*75.

So using the same method:

82.50=75+y%*75

y%*75=82.50-75=7.5

we can make the calculations, but clearly 7.5 is 10% of 75

Answer: 10% gain.
