There will be 130 nickels and 90 dimes. 100 nickels is 5 dollars. 90 dimes are 9 dollars. And then there will be 30 left. 30 dimes isn’t 1.50$ bur 30 nickels is 1.50$ so you add the 30 to the nickels and it’ll be exactly 15.50$.
Hey there :)
9( n - 4 ) - 4n ( n - 4 )
We can take ( n - 4 ) as common as both are getting multiplied by ( n - 4 )
We can join 9 - 4n together
Therefore, the final answer will be ( n - 4 )( 9 - 4n )
Answer:
rid, eid, sir, dis, sod, sec, nod
3x+ 4 = 20
First you SUBTRACT 4 from both sides . Since these are inequalities we do reverse PEMDAS (Parentheses , Exponents , Multiply , Divide , Add ,Subtract). Then you will have an equivalent equation of
3x=16
Now we have to isolate X . So we divide 3 by both sides . Which will get 5.3333...
Therefore , The answer will be
The first step in solving the equation is to<u> SUBTRACT </u> from each side . This is an example of the <u>subtraction</u> property of <u>EQUALITY</u>
Distance between two points =
√(3−−2)2+(3−3)2= √52+02= √25+0=
√25= 5
Distance between points (-2, 3) and (3, 3) is 5
