B. 21 Bo; 23 Erica
C. 16 Bo; 28 Erica
D. 19 Bo; 25 Erica

Answers

Answer 1

Answer:

Answer: D. 19 Bo; 25 Erica

Step-by-step explanation:

Let x represent the number of yoga classes that Bo teaches in a week.

Let y represent the number of yoga classes that Erica teaches in a week.

Between the two of them, they teach 44 yoga classes each week. This means that

x + y = 44 - - - - - - - - - - -1

If Erica teaches 13 fewer than twice as many as Bo, it means that

y = 2x - 13

Substituting y = 2x - 13 into equation 1, it becomes

x + 2x - 13 = 44

3x = 44 + 13 = 57

x = 57/3 = 19

y = 2x - 13 = 2 × 19 - 13

y = 25

Mike won 7 of his wrestling matches, lost 6 matches, and tied 2 matches. What percent of all of Mike's matches did he win?

Answers

Mike won 46.67% of all of his matches.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. Moreover, it is indicated by the symbol "%."

The total number of matches that Mike wrestled is:

Total matches = number of matches won + number of matches lost + number of matches tied

Total matches = 7 + 6 + 2

Total matches = 15

To find the percentage of matches that Mike won, we can use the formula:

Percentage = (Number of matches won / Total number of matches) x 100%

Plugging in the values we know, we get:

Percentage = (7 / 15) x 100%

Percentage = 0.4667 x 100%

Percentage = 46.67%

Therefore, the Percentage = 46.67%.

Answer:

Mike won 46.67% of his matches

Step-by-step explanation:

Mike participated in a total of 7 + 6 + 2 = 15 matches.

The percentage of matches that Mike won can be found by diving the matches he won by the total number of matches and multiplying it by 100 to convert the decimal to a percentage.

(7/15) x 100% ≈ 46.67%

Therefore, Mike won approximately 46.67% of his matches.

Using the table of ordered pairs, which equation shows the linear relationship between the x and y values? ---- ----

x|y

3|7

---- ----

A. y = x + 4

B. y = -x

C. y = x - 4

D. y = 4 - x

Answers

Answer:

y = x + 4

Step-by-step explanation:

y = mx + b (m = slope; b = y-intercept)

I used 2 points (-2 , 2) and (1 , 5) to calculate the slope of the line

m= (y₂ - y₁)/(x₂ - x₁)

(5-2)/(1--2) = 3/3= 1

y = 1x + b

using point (1, 5)

5 = 1(1) + b

5 = 1 + b

b = 5-1

b=4

y= 1x + 4 or simply y= x + 4

Answer:

A y = x + 4
