B= - 6/5
Step-by-step explanation:
Answer:
x=21
Step-by-step explanation:
Following the vertical angles, we can assume that the equation that has x and 87 are equal to each other. From then, you set them equal to each other and solve for x.
87=4x+3
84=4x subtract 3 from both sides
21=x divide by 4 to get the x alone on both sides
Answer:
The correct answer is B.
We have 4 / 10 = ( 2 x 2 ) / ( 2 x 5 );
6 / 15 = ( 3 x 2 ) / ( 3 x 5 );
8 / 20 = ( 4 x 2 ) / ( 4 x 5 );
