Add or subtract the following mixed numbers. first change each mixed number to an equivalent improper fraction. then
find a common denominator, and proceed as before. leave your answer as an improper fraction. be sure your answers
are reduced to lowest terms.
1/5 + 2 1/3

answer: 2.5

step-by-step explanation: to write 2.5 as a fraction you have to write 2.5 as numerator and put 1 as the denominator. now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

2.5 = 2.5/1 = 25./10 = 253./100 = 2533./1000 = 25333./1 = 25./1 = 25./1 = 25./1 = 25.333/1 = 25.33/1 = 25.3/1 = 25/1

and finally we have:

2.5 as a fraction equals 25/1

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
