Fifty people were surveyed about their favorite flavor of frozen yogurt. the results of the survey are displayed in the circle graph.

how many people prefer strawberry?

Hence, 9 people prefer strawberry.

Step-by-step explanation:

Total number of people that were surveyed are : 50.

From the circle diagram or circle graph the number of people according to there choices of favorite flavors of Frozen Yogurt is given as:

       Flavors                     Percent

Peanut Butter                   20%

Banana                               4%

Vanilla                                22%

Chocolate                            36%

Hence, the percent of people that  prefer Strawberry is 18%

i.e. 18% of total people surveyed.

i.e. 18% of 50

Hence, the number of people who prefer strawberry is:

9

i will answer your question though.

{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

answer:   {x = -1/2 ,   y = -1
