17 = -7z + 3

What is z

z = -2

Step-by-step explanation:

Let's solve your equation step-by-step.

17=−7z+3

Step 1: Flip the equation.

−7z+3=17

Step 2: Subtract 3 from both sides.

−7z+3−3=17−3

−7z=14

Step 3: Divide both sides by -7.

−7z−7=14−7

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
