Answer:

mA=56 degrees

Step-by-step explanation:

Complementary angles adds up to 90 degrees. This imply that

(7x+28)+(8x+2)=90

From this equation, we can find x:

15x+30=90\\15x=90-30\\15x=60\\x=\frac{60}{15}\\x= 4

Now, we can substitute the value for x into the angle mA:

mA=(7*4+28)\\mA=(28+28)\\mA=56

A scatter plot was constructed and a line of best fit was drawn, 25x 80. What is the equation of this best line of fit?
Tcecarenko [31]

Answer:

y = 5x + 25

Explaination:

To get the equation of a line, first get the slope of the line.


Slope = (change in y)/(change in x)


          = (60-30)/(7-1)


          = 30/6


            = 5


Now use one point in the line (4,45) and a general point (x,y).


Slope = (change in y)/(change in x)


    5 = (y - 45)/(x - 4)


    5(x - 4) = (y - 45)


  5x - 20 = y - 45


y = 5x -20 + 45

The answer is 10/3. Because you have 3 wholes and 1/3 so, 3x3 is 9 and you still have the extra 1 so 9+1=10 therefore your answer would be 10/3
