What percent of 1 3/5 is 0.2 and what percent of 2 is 0.2?

saveliy_v [14]

1 3/5 = 8/5
.2=2/100

make an equality:
x/(8/5)=2/100
it kinds looks weird on here but write it out on paper

then cross multiply:
100x=(2)(8/5)
100x=16/5

now divide each side by 100:
x=4/125

same for the second one:
make an equality:
x/2=2/100
cross multiply:
100x=(2)(2)
100x=4
x=1/25

in a proportional relationship the ratio y/x is constant. Show that this ratio is not constant for the equation y=a-14

Colt1911 [192]

To show that the ratio $\frac{y}{x}$ is not constant for the function $y=a-14$ we only need to evaluate this function at 2 points and then show that the ratio is not the same for those two points. Note that here $a$ represents $x$ .

To find the counter examples here, I will use the values $a=20$ and $a=28$ . For $a = 20$ , the equation tells us that the output is

$y=20-14=6$ . For this value of $a$ the point is point is $(20,6)$ . The ratio $\frac{y}{x} =\frac{6}{20}$ . For the $a=28$ , $y=28-14=14$ . For this value of $a$ the point is $(28,14)$ . The ratio $\frac{y}{x} =\frac{14}{28} =\frac{1}{2}$ . Clearly this ratio is not constant for all ordered pairs.

Name ALL the sets of numbers to which -28 belongs.

miv72 [106K]

A. integers, c. integers rationals, and d. integers rationals reals. it would not be a natural number, because a natural number is a positive number (and sometimes 0)
