The general form of a quadratic equation is that which is expressed in a form,
                                     ax² + bx + c = 0 
To write the equation in its general form, eliminate the decimal by multiplying the equation by 10. It now becomes,
                                        3x² + 50x - 70 = 0
The value of b is therefore 50 and the answer is the second choice.

Mary wants to put 1/10 of a kilogram of bird seed in each of the bird cages in her pet shop. She has 3/10 of a kilogram of bird
alex41 [277]

Answer:

  A)  3

Step-by-step explanation:

If you simply look at the given numbers, it should be pretty clear that 3 tenths is 3 times 1 tenth.

When Mary puts 1/10 kg in each cage, she can do that for 3 cages with 3/10 kg of bird seed.

__

If you let c represent the number of cages, then the amount of bird seed used will be (1/10)c. This will be equal to the amount available when we use it all for filling cages:

  (1/10)c = (3/10)

Multiply both sides of the equation by 10:

  c = 3

Mary can fill 3 cages with available seed.
