Tell whether the ratios form a proportion. 2/5,40/16

Mathematics
1 answer:
lisabon 2012 [21]3 years ago
5 0

Answer:

No, those ratios are not proportional.

Step-by-step explanation:

The reason for them not being proportional is because 2/5 is already in its simplest form and 40/16 in its simplest form is 5/2, resulting in them not being equivalent meaning that they are not proportional.

I need help on all of these
lord [1]

well #7 is a solution.

y= 9x (4,36)

9 times 4 = 36

36/9=4

so the ordered pair is a solution.

y=3x-5 (7,16)

3 times 7 -5= 16

so once again the ordered pair is a solution.


Hoped this helped.

Write an equation of each line in standard form with integer coefficients.<br> 4. y = 2.4x + 1.8
Nadusha1986 [10]

Answer:

<h2>12x - 20y = -9</h2>

Step-by-step explanation:

The standard form of an equation of a line:

Ax+By=C

We have

4y=2.4x+1.8

Convert

4y=2.4x+1.8          <em>multiply both sides by 10</em>

40y=24x+18          <em>subtract 24x from both sides</em>

-24x+40y=18            <em>change the signs</em>

24x-40y=-18          <em>divide both sides by 2</em>

12x-20y=-9
