Ginger is starting a 330-page book. Suppose she reads for 4 hours and averages 35 pages per hour. a. How many pages will she read in 4 hours?
b. After 4 hours, how many pages will she still have to read to finish the book?

140 and 190

Step-by-step explanation:

Each hour she reads 35 pages.

So, lets add the amount of pages she reads every hour 4 times which gives us the answer for 4 hours.

35+35+35+35 = 140

or

35x4=140

She reads 140 pages in 4 hours.

To find how many pages she has left is,

330-140=190

She has 190 pages left to read

(new to so not sure if its right)

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
