Mrs. Sahd distributes pencils and papers to students in the ratio of 2 pencils to 10 sheets of paper. Three of these ratios are
IRINA_888 [86]

The ratio that is not equivalent is B. 7:15

The reason why it's not equivalent because for the other ratios:

1:5 could be turned into 2:10 by multiplying 1 and 5 by 2.

4:20 could turn into 2:10 by dividing both numbers by 2.

And 8:40 could be divided by 4 to get 2:10.

But you can't do anything to 7:15 to make it 2:10.

     OR

9 + 9 = 18

See? Twice a number is eighteen. You can use any of my equations to get eighteen

Find the solution to the equation below.<br> 2x^2+3x-20=0
mariarad [96]

Answer:

  x = -4, 5/2

Step-by-step explanation:

A quadratic can be solved may ways, including graphing, factoring, and the quadratic formula. You can also check possible answers by making use of the relationships between solutions and the coefficients.

__

A graph is attached. It shows the solutions to be -4 and 5/2.

__

When factored, the equation becomes ...

  (2x -5)(x +4) = 0 . . . . . has solutions x=-4, x=5/2 (these make the factors zero)

__

Using the quadratic formula, the solutions of ax^2 +bx +c = 0 are found from ...

  x = (-b±√(b²-4ac))/(2a)

  x = (-3±√(3²-4(2)(-20))/(2(2)) = (-3±√169)/4 = {-16, +10}/4

  x = {-4, 5/2}

__

For ax^2 +bx +c = 0, the solutions must satisfy ...

  product of solutions is c/a = -20/2 = -10

Only the first and last choices have this product.

  sum of solutions is -b/a = -3/2

Only the first choice (-4, 5/2) has this sum.
