The value of y directly proportional to the value of x. If y= 8 when x= 12, what is the value of y when x= -15? The value of y directly proportional to the value of x. If y= 3 when x= 24, what is the value of y when x= -8?

The value of y should be -10

Step-by-step explanation:

If x and y are proportional, then 8/12=y/-15

The fractions just show the y values over the x values

Cross multiply to get 12y= -120

y= -10

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70

7000
