Is 6/12 and 15/30 proportional?

sveticcg [70]

Answer:

yes

Step-by-step explanation:

6 is half of 12. 15 is half of 30. The ratios are equal, so the fractions are proportional.

Answer: yes

Also, you can reduce both fractions.

Divide the numerator and denominator of 6/12 by 6 to get 1/2.

Divide the numerator and denominator of 15/30 by 15 to get 1/2.

Since both fractions reduce to 1/2, 6/12 and 15/30 are equivalent fractions and are proportional.

Which graph shows the solution to the system of linear inequalities? x – 4y < 4 y < x + 1 Image for option 1 Image for opt

slava [35]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

$x-4y$ ----> inequality A

solve for y

$-4y$

$4y>x-4$

$y> (x/4)-1$

The solution of the inequality A is the shaded area above the dashed line

The slope of the dashed line is positive

The y-intercept is the point $(0,-1)$

The x-intercept is the point $(4,0)$

$y< x+1$ ----> inequality B

The solution of the inequality B is the shaded area below the dashed line

The slope of the dashed line is positive

The y-intercept is the point $(0,1)$

The x-intercept is the point $(-1,0)$

Using a graphing tool

The solution of the system of inequalities in the attached figure

The answer is B because on the graph you start at $3.00 then you add $5.00 per hour so it goes up 5/1 per hour on the graph.
