You teach an arts and crafts class at your local library. There are 12 girls and 11 boys registered for the class. You need to purchase supplies that will cost $5 per student.

How much will it cost to purchase the supplies?

$28
$67
$71
$115
$192

$115

Step-by-step explanation:

first you would add the total number of students

12+11=23

Then you would multiply that by 5 since its $5 for every student

23 x 5 = 115

115

12 + 11 =23

23x 5= 115

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

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
