85 x 80 = 6800

6800/100 = 68

x = 68

Cross multiply then flip equation
85 * 80 and x * 100
6800 = 100x
100x = 6800

Now divide each side by 100
100x ÷ 100 = 6800 ÷ 100
x = 68

AC, DF, and GI are parallel. Use the figure to complete the proportion.

JA / JC = AB / BC because, as we can see in the picture above, it's the same proportion. So the answer is the fourth one - BC.

I hope that's what you meant and if so that it will help you :)

Factor expression 9x^6- 16y^6

Darya [45]

Using a^2-b^2 = (a-b)(a+b) you can factor the expression:
(3x^3-4y^3)(3x^3+4y^3)

Can a chord also be classified as a radius? Explain your answer.

Sveta_85 [38]

No it can't really because a chord stretches across the whole circle (if you look up a chord online you'll see) and the radius is only half of the circle. Hope this helped:)

The midpoint of AB is M(3,-1).If the coordinates of A are (8,4) what are the coordinates of B

Alchen [17]

Answer:

B(-2,-6)

Step-by-step explanation:

The midpoint of AB is M, then A(8,4), M(3,-1)

So we can find:

$x_{B} =2x_{M} -x_{A}= 2*3-8= -2\\y_{B}= 2y_{M} -y_{A} = 2*(-1)- 4= -6\\$
