Which is 3x + 7 for x equals 3​

x=3/10

Step-by-step explanation:

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

3x+7x=3

Step 1: Simplify both sides of the equation.

3x+7x=3

(3x+7x)=3(Combine Like Terms)

10x=3

10x=3

Step 2: Divide both sides by 10.

10x /10  = 3/10

x=3/10

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)
