I think you're suppose to multiply the wholes first so 3 x 4 is 12 so you're really dealing with...

12 1/8... then multiply the bottom by the whole...

12 x 8 is 96 now add the numerator and keep the denominator...

97/8...

If I'm incorrect and your process is first then you are correct how you broke it down.

It is incorrect because 3 1/8 times 4 is 12 1/2

28/8 or 3 1/2 times 4/1 or 4 is 12 1/2

100/8 divided by 4 is 3 1/8, and is not 12 1/2

For 12, the answer would be Y is greater than or equal to 8. If you subtract 193 from both sides of the inequality, you are left with y and 201-193=8. So the overall inequality would look like y>=8. Therefore, you would shade from 8, and everything greater than 8, with a closed circle.

Which methods could you use to calculate the x-coordinate of the midpoint of a horizontal line segment with endpoints at (0, 0)
SpyIntel [72]
You could add the two x-coordinates together (in this case, 0 and 20) and then divide them by 2 to get an x-coordinate of 10 for their midpoint.

There are 50 deer in a particular forest. The population is increasing at a rate of 15% per year. Which exponential growth funct
NemiM [27]

Answer:

The expression that represents the number of deer in the forest is

y(x) = 50*(1.013)^x

Step-by-step explanation:

Assuming that the number of deer is "y" and the number of months is "x", then after the first month the number of deer is:

y(1) = 50*(1+ 0.15/12) = 50*(1.0125) = 50.625

y(2) = y(1)*(1.0125) = y(0)*(1.0125)² =51.258

y(3) = y(2)*(1.0125) = y(0)*(1.0125)³ = 51.898

This keeps going as the time goes on, so we can model this growth with the equation:

y(x) = 50*(1 - 0.15/12)^(x)

y(x) = 50*(1.013)^x
