The percent bar graph below shows what day of the week students have music class. The graph displays data collected from 200 students. How many more students have music class on Tuesday than on Friday?

50

Step-by-step explanation:

To take the percentage of a number, you move the decimal place to the right twice. Then, multiply the number by the now decimated percentage.

In this problem, 200 x .35 gives you 70. Then, 200 x .10 gives you 20. Do 70-20 and you get 50.

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
