Answer:

Thus, 3/2 in, or 1.5 in, represents 1 mile.

Step-by-step explanation:

"3 quarter inches to the half mile" can be expressed as "3/4 inch to 1/2 mile."

Write and solve an equation of ratios to obtain the unit rate in inches/mi:

3/4 in x

---------- = ---------

1/2 mi 1 mi

Cross multiplying, we get 3/4 in-mi = (1/2) mi*x.

Solve this for x by mult. both sides by 2:

6/4 in-mi = x mi

and then dividing both sides by mi:

(6/4) in-mi

--------------- = 3/2 in

Thus, 3/2 in, or 1.5 in, represents 1 mile.

Which ratio is porportional to 18/21? A.2/3 B. 30/35 C. 36/48 D.1/3

defon

You can solve this problem by applying the proccedure below:

You have:

a) 18/21=2/3
18x3/21x2
36≠42 (2/3 is not proportinal to 18/21).

b)18/21=30/35
18x35/21x30
630=630 (30/35 is proportional to 18/21)

c)18/21=36/48
18x48/21x36
864≠756 (36/48 is not proportinal to 18/21)

d)18/21=1/3
18x3/21x1
54≠21 ( 1/3 is not proportinal to 18/21)

Therefore, you can conclude that the correct option is: B.30/35

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:y >

pantera1 [17]

Answer:

Part A: The graph of given inequality is shown below.

Part B: The point (4,6) is not a solution of given system of inequalities.

Step-by-step explanation:

Part A:

The given inequalities are

$y>2x+3$

$y$

The related equation of given inequalities are

$y=2x+3$

$y=-\frac{3}{2}x-4$

Put x=0, to find the y-intercepts.

$y=2(0)+3=3$

$y=-\frac{3}{2}(0)-4=-4$

Put y=0, to find the x-intercepts.

$0=2x+3\Rightarrow x=-\frac{3}{2}$

$0=-\frac{3}{2}x-4\Rightarrow x=-\frac{8}{3}$

The x and y-intercepts of first line are (0,3) and (-1.5,0) respectively. The x and y-intercepts of second line are (0,-4) and (-2.667,0) respectively.

Check the given inequality by (0,0).

$0>2(0)+3$
