Answer:

x = $\frac{42}{5}$

Step-by-step explanation:

Given

19 - $\frac{5x+6}{4}$ = 7 ( subtract 19 from both sides )

- $\frac{5x+6}{4}$ = - 12

Multiply both sides by - 4 to clear the fraction and the negative signs

5x + 6 = 48 ( subtract 6 from both sides )

5x = 42 ( divide both sides by 5 )

x = $\frac{42}{5}$

Can you bisect an angle using only a compass and a straight edge

ahrayia [7]

Answer:

yes

Step-by-step explanation:

bisect = dividing it into two equal parts

if you were to line the angle up with the north (or really any line of the compass), you could find the center (you could find where two lines [the same distance from north] are on equal sides of north, or you could just find the center of the angle from sight)

and with the straight edge, you could easily divide the angle into two equal halves
