You practice piano for 50 minutes each weekday and for 40 minutes on each weekend day. how many hours per week do you practice?

330 minutes a week

Step-by-step explanation:

50 x 5= 250 then add 80 because 40 x 2 is 80 and get 330

five and a half hours.

Step-by-step explanation:

50 minutes x 5 days = 250 minutes

40 minutes x 2 days = 80 minutes

250 +80 = 330 minutes

330 minutes/60 minutes in an hour =5.5

answer is 5:30 hrs

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
