Part a: solve the equation 5(x + 2) = 6x + 3x − 14, and show your work.
part b: use this list of properties to justify each step of your math work. justifications may be used more than once if needed.
distributive property
subtraction property of equality
combine like terms
multiplication property of equality
division property of equality
given
addition property of equality

for this case we must solve the following equation:

adding similar terms on the right side of the equation we have:

applying distributive property on the left side of the equation:

we subtract 9x from both sides:

we subtract 10 from both sides:

we divide between -4 on both sides:

x = 6

combine like terms

sorry i dont know my friend

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
