A ribbon is 4 m long. How many pieces each 30 cm long can be cut from the ribbon?​
EleoNora [17]

Answer:

13 pieces

Step-by-step explanation:

First we convert 4m into cm :

1m = 100cm

4m = 400cm

Now we need to figure out how many 30s go into 400 :

400 ÷ 30 = 13 remainder 10

So 13 pieces can be cut from the ribbon

Hope this helped and have a good day

Help on college algebra, question is on the picture!
kodGreya [7K]
\frac{7x+1}{x-2} + \frac{2}{x} = \frac{-4}{ x^{2} -2x} is given 
here , \frac{7x+1}{x-2} + \frac{2}{x} = \frac{-4}{ x^{2} -2x} 
or, \frac{7x^{2} +x +2x-4 }{x(x-2)} = \frac{-4}{ x^{2} -2x}
or,\frac{7 x^{2} +3x-4}{ x^{2} -2x} = \frac{-4}{ x^{2} -2x}
or,7x²+3x-4=-4
or,7x²+3x=0
or,x(7x+3)=0
Either,x=0| Or,7x+3=0
                |or,7x=-3
                |or,x=\frac{-3}{7}
So , the solution set is S={0,-\frac{3}{7}}
