The diagram shows 3/4 of a fraction strip shaded. Mary erases some of the shading to show 5/8. Explain in the steps the took to shade 5/8 of thr fraction strip. a. She divided the fraction strip into 3/4
parts
b. She converted 3/4 into a fraction with a numerator of
.3/4= -/8
c. -/8-5/8 = -/8 She erased. eight of the shaded area
draw a revised model to show the diagram after Mary erases the fraction of the area shown in the last step

Whats the name of the vertical axis

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y < 4x − 8 y is greater than or equal to negative 5 over 2 times x plus 5 part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points) part b: is the point (5, −8) included in the solution area for the system? justify your answer mathematically. (4 points)

You are standing next to a really big circular lake. you want to measure the diameter of the lake, but you don't want to have to swim across with a measuring tape! you decide to walk around the perimeter of the lake and measure its circumference, and find that it's 400\pi\text{ m}400? m. what is the diameter dd of the lake?
