d

step-by-step explanation:

an inequality is an expression which means more than one number is a solution. we graph the solutions on a number line to show all possible values. we graph using circles and arrows.

this is a filled in circle on -2 so this is . this means only answers c and d are options.

answer d points to the right.

simplify brackets

8 - 2a - 7 = a + 40

simplify 8 - 2a - 7 to -2a + 1

-2a + 1 = a + 40

add 2a to both sides

1 = a + 40 + 2a

simplify a + 40 + 2a to 3a + 40

1 = 3a + 40

subtract 40 from both sides

1 - 40 = 3a

simplify 1 - 40 o -39

-39 = 3a

divide both sides by 3

-39/3 = a

simplify 39/3 to 13

-13 = a

switch sides

a = -13

created after the great insurrection of 10 august 1792, it was the first french government organized as a republic, abandoning the monarchy altogether. the convention sat as a single-chamber assembly from 20 september 1792 to 26 october 1795 (4 brumaire iv under the convention's adopted calendar). hope this : )
