Is 8/24 greater or 8/20
Afina-wow [57]

Answer:

8/20

Step-by-step explanation:

the 8s may be the same, but because the denominator 20 is smaller than 24, 8 takes up more of it. another way to check is that 8/24 as a decimal is .33 repeating, but 8/20 as a decimal is 0.4.

0.4 is more than .33 repeating. reaffirming that 8/20 is bigger

Can someone help me out and show me the work to solve this question
Alina [70]

Answer:

x = 105

y = 64

Step-by-step explanation:

Inside the four sided figure, the angles must add to 360. So 121+70+x+y = 360. You also know that a straight line is 180. This means 116 + y = 180. Using them together you can solve for the variables. Begin by substituting the equation 116 + y = 180 into the other equation.

116 + y = 180 converts to y = 180-116 = 64.

Substitute y = 64 into 121 + 70 + x + y = 360.

191 + x + 64 = 360

255 + x = 360

x = 105
