B. 20 sixth graders, 35 seventh graders, 45 eighth graders

C. 45 sixth graders, 45 seventh graders, 45 eighth graders

D. 20 sixth graders, 20 seventh graders, 20 eighth graders

maya’s expression will generate the wrong sum because she violated the commutative property.

step-by-step explanation:

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.

answer: i ! the answer is   9000 seconds, also d

hope i
