X = 50 because x = number of text messages sent

0.2x+40=50

0.2x = 10

5(0.2x) = 5(10)

x = 50

Therefore, 50 text messages would have to be sent or received in order for the plans to cost the same each month.

What value of d will make this system have the same solution?<br> -3x + 7y = -1<br> dy = 3
Dima020 [189]

The value of d which will.make this system have the same solution is; d = 21/(3x -1)

First, we must make y, the subject of the formula in each case as follows;

  • y = (3x -1)/7. and
  • y = 3/d.

In essence, by equating y to y in both equations; we have;

  • (3x -1)/7 = 3/d

By Cross-product; we have;

  • (3x -1).d = 21

  • d = 21/(3x -1)

ANSWER QUICK<br> What are the values of a, b, and c in the quadratic equation 0=1/2x^2-3x?
Inga [223]

Answer:

a=\dfrac{1}{2}\\ \\b=-3\\ \\c=0

Step-by-step explanation:

The general form of the quadratic equation is

ax^2+bx+c=0

You are given the quadratic equation

0=\dfrac{1}{2}x^2-3x

It can be rewritten in standard form as

\dfrac{1}{2}x^2-3x=0

Hence,

a=\dfrac{1}{2}\\ \\b=-3\\ \\c=0
