Mrs. Schellhaas spent $14.00 of the $20.00 she has on her Starbucks gift card. Which decimal represents the fraction of the $20.00 she spent

0.7 or 70%

Step-by-step explanation:

Step 1 : Find what percent 14 is of 20. Set up an equation to solve for x.

14 = x (20)

Divide by 20 on both sides.

14 divided by 20 = 0.7

So the decimal which represents the fraction of the 20 bucks she spent is 0.7

Bonus step : If you want to find what is 0.7 in percentage form, then simply convert. 70/100 = 70 percent.

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1
